4 6 9 How to find the least common multiple of three numbers

Find the least common multiple of 4 and 6: 12

Process: Divide by 2 (non-1 least common divisor) at the same time to get 2, 3, no non-1 least common divisor, stop, the least common multiple is 2*2*3=12

Find the least common multiple of 12 and 9: 36

Process: Divide by 3 (non-1 least common divisor) at the same time to get 4,3, there is no non-1 least common divisor, stop, the least common multiple is 3*4*3=36

2 l 4 6 9

3 l 2 3 9

The least common multiple of three numbers.

Let's not talk about the regular solution, that is, we will use the common divisor to reduce until we can't divide it, and then multiply the common divisor.

Let's talk about a simple way to find the least common multiple of three numbers.

Example 4 6 9

Let's see if there are three common divisors, which are obviously not in this example.

Then look at which two numbers have no common divisor, obviously 4 9. And 4,6 has the least common divisor 24x9=36, and then see if it is a multiple of 6.

Yes, the answer is 36

Divide the common divisor by multiplying by the number that cannot be divided.

Divide by 2 to 2 for 2 3 9

2 3 9 is the same as dividing 3 to make 2 1 3

i.e. 2x3x2x1x3=36

Mine in the most detailed.

Because 3 is the factor of 6, the least common multiple of 3, 5, and 6 is the least common multiple of 5 and cherry blossom or 6, that is, 5*6=30 (because the branches are divided into 5 and 6 are cozymic).

3, 5, a common multiple of 6.

There are an infinite number of them, the smallest of which is 30, 6 = 2 3, and finally 2x3 5 = 30

3＝1×3；4＝2×2；6＝2×3。So the least common multiple of is 2 2 3 l2.

Analysis: Since three numbers are coprime, the least common multiple of the three numbers is their product, i.e.: 7x4x9=252

Answer: The least common multiple of the three numbers is 252.

The numbers 7, 4, and 9 are coprime numbers. Their least common multiple is the product of the multiplication of their three numbers.

Their least common multiple is 252.

As can be seen from the question, there is no common factor for the three numbers, so their least common multiple is 7*4*9=252

7 is coprime with 4, coprime with 9, and 4 with 9, so the least common multiple of these three numbers is their product, i.e., 7x4x9 252.

252, multiply without a common factor.

Multiples of 4: 4

36] Multiples of 6: 6

36] Multiples of 9: 9

36] So 4

The most popular multiple of 9 is 36

Multiples of 4 are: 4 8 12 16 20 24 28 32 36 40 ...Multiples of 6 are:

6/12/18/24/30/36/42/28 ..Multiples of 9 are: 9 18 27 36 45 54 ...

So the least common multiple of 49 is 36

The least common multiple is 36

The least common multiple of 36

The least common multiple of is 36The equation is as follows: 2 l 49 3 l 2

3 lcm=2x3x1x2x3 =36

Reference: I will first place 4

9 is expressed as a multiplication of prime factors: 4 = 2 x 2 6 = 2 x 3 9 = 3 x 3 After multiplying each of them by the number of occurrences of the tanhuai so 4

Least common multiple of 9 = 2 x 2 x 3 x 3 = multiple of 364: 4

36] Multiples of 6: 6

36] Multiples of 9: 9

36] So 4

The least common multiple of 9 is 36

The least common multiple of is 36

The least common multiple of 3*2*1*2*1=12

It's as simple as that.

is 12, decompose the prime factor, 3 is the prime number, 4 2*2, 6 2*3, so the least common multiple is 3*2*2=12

The least common multiple of these four numbers is 126. Simple Mu Enlightenment Algorithm:

8 is a common multiple of 2, 9 is a common multiple of 3, 10 is a common multiple of 5, and the common multiple of 8 and 9 contains 6.

So just count the common multiples of 7, 8, 9, and 10.

is 7*2*2*2*3*3*5=2520.

Scope of application: A prime number is a number that is not divisible by numbers other than 1 and its own number; The nth power of the prime number x is that the nth power of the prime number can only be divisible by the n and below x, 1 and its own number. So, give a definition of the most durable small male multiple:

The least common multiple of the number of s is the product of the highest power of the prime factor contained in the number of s.

Let's analyze it first.

6 is 3 times that of 2, and the most macroscopic cover is only considered 6, that is, the least common multiple.

The least common multiple of 9 and 6 is 18

Look at 18 and 7 mutual.

So the least common multiple is.

is a prime number. Therefore, the least common multiple is: 2 3 3 7 = 126

Minimum multiples of the manuscript.

Two identical numbers are only multiplied by one, and the meaning of the note is that when two are the same, if three are the same, the two are only multiplied once and then multiplied by the other.

For example, if there are 3 2s in the above question, you need 2 2, or use the short hole to remove the filial piety method.

Easiest.

4, 5, and 9 are coprime numbers, and the least common multiple is 4*5*9=180.
