How to calculate short division 5, how to calculate short division

Short division is a method of finding the greatest common factor and can also be used to find the least common multiple.

The method of finding the greatest common factor of several numbers starts with the method of observation and comparison, that is, first find out the factor of each number, then find the common factor, and finally find the greatest common factor in the common factor.

Later, the prime factor decomposition method was used to decompose the factors of the two numbers separately and then perform the operation. It then evolved into short division. The short division operation is to divide a divisor by a prime number that can be divided by it, and so on, until the quotient is a prime number.

Extended Materials. 1. Short division to find the approximate number, first use the common divisor of these numbers to continuously remove, until all the quotients are co-qualified, and then multiply all the divisors together, and the product obtained is the greatest common divisor of these numbers.

For example, find the greatest common divisor of ) = 2 3 2 = 12

2. Short division to find the least common multiple, first use the common divisor of these numbers to remove each number, and then use the common divisor of the partial number to remove, and remove the number that cannot be divisible, until every two numbers in all the quotients are coprime, and then multiply all the divisors and quotients, and the resulting product is the least common multiple of these numbers.

For example, find the least common multiple of ) = 3 2 2 5 3 = 180

Hello, now I am here to answer the above questions for you. Short division.

1. Short division is a method of finding the greatest common divisor, and can also be used to find the least common multiple.

2. The method of finding the greatest common divisor of several ears and hunger numbers is to use the method of observation and comparison at the beginning, that is: first find out the divisor of each number, then find the common divisor, and finally find the greatest common divisor in the common divisor.

3. The short division sign is the division sign.

Upside down. 4. Short division is to write the divisor in division.

where the prime factor common to two numbers is written.

Then the quotient of two numbers divisible by the common prime factor is dropped, and then divided, and so on, until the result is co-prime.

Until (two by two).

5. When guessing that God reuses short division to calculate multiple numbers, the factors that exist in any two of them must be calculated, and the other numbers that do not have this factor will fall as they are.

6. Until every two remaining are mutual.

7. Multiply the greatest common divisor by one side and multiply by half if you find the least common multiple.

8. Turn leftTurn right.

With short division, you can use the least common multiple and the greatest common factor of n numbers.

First of all, let's look at these 4 numbers, whether there is a common factor, if so, directly find the 4 numbers.

If there is no common factor, first look at how many numbers have a common factor, find the least common multiple, and then use the least common multiple with the remaining numbers to see if there is a common factor, and so on.

For example: the first type: 4 numbers have common factors: 2, 4, 6, 82, 4, 6, 8 The common coprime factor of the common disturbance delay is: 2, 2, the greatest common factor is: 2, and the least common multiple of the least common multiple is :

Second, 3 of the 4 numbers have common factors, 2, 4, 6, 39 first find 2, 4, 6.

The common prime factor of 2, 4, and 6 is: 2, and the greatest common factor is: 2

The least common multiple is:

Seek again 12 and 39.

The coprime factor of 12, 39 is 3, and the greatest common factor is: 3

The least common multiple is:

So, the greatest common factor of 2, 4, 6, 39 is: 3 2=6 The least common multiple is: 156

Hello! I see your question, let me answer it. What is the formula for short division, right? Short division is a commonly used division method, usually used for division of integers, which can help us derive quotients and remainders more quickly.

The formula for short division can be written in the following form: Dividend = Divisor Quotient + Remainder Field. Where, the dividend refers to the number that needs to be divided, the divisor refers to the number to be divided by the dividend, the quotient refers to the quotient of the dividend and the divisor, and the remainder refers to the number that remains when the divisor is not divisible by the dividend.

Specifically, we can calculate division using short division by following these steps:

First, write the divisor on the far left side of the dividend and divide them to get the quotient, with the remainder being zero.

Write the quotient below the dividend.

Write the next number on the far right of the remainder and divide them to get the quotient, with the remainder being zero.

Repeat until the aftermath reaches zero or is less than the divisor.

For example, if we want to calculate 156 4, we can use short division to do the calculation. First, write 4 on the far left of 156 to get a quotient of 39 with a remainder of 0. Then, write quotient 39 under 156.

Next, write the next number 2 on the far right of the remainder to get 42, divide them to get the quotient 10, and the remainder is 2. Finally, write the quotient 10 below with a remainder of 2 to get the final result of 39 with a remainder of 2.

Answer: When using short division to find the greatest common factor and the least common multiple of two numbers, divide from the minimum prime factor common to the two numbers and continue to divide until the two quotients obtained by the division are co-primed.

For example, find the greatest common factor of 12 and 18 and the least common multiple of Bi Chong.

Short division is a method of finding the greatest common divisor of the stroke, and can also be used to find the least common multiple. The method of finding the greatest common divisor of several numbers starts with the method of observation and comparison, that is, first find the divisor of each number, then find the common divisor, and finally find the greatest common divisor in the common divisor.

The short division sign is the division sign reversed. Short division is to write the prime factor common to two numbers where the divisor is written in division, and then drop the quotient of the two numbers divisible by the common prime factor, and then divide, and so on, until the result is co-prime (two pairs of co-prime). When calculating multiple numbers with short division, the factors that exist in any two of them are calculated, and the other numbers that do not have this factor fall as they are.

Until the remaining two, every two are mutually reciprocal and laughing. Multiply the greatest common divisor by one side and multiply by half if you find the least common multiple.
