What are all the factors of 84? What is the factor of 84?

The full factors of 84 are (1,2,3,4,6,7,12,14,21,28,42,84).

Analysis: A method of finding all the factors of a number.

1.Decompose prime factors.

As in this question, the prime factors of 84 are: 2, 2, 3, 7

Then, the factor of 84 has 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, 84.

2.One-to-one correspondence method, find a pair.

As in this question, 84 = 1 84 = 2 42 = 3 28 = 4 21 = 6 14 = 7 12

So, all the factors of 84 are: 1, 84, 2, 42, 3, 28, 4, 21, 6, 14, 7, 12.

To put it simply, there are 12 factors of 84. They are .

Among the multiples of 3 are: 3, 6, 12, 21, 42, 84.

The multiples of 2 are: 2, 4, 6, 12, 14, 28, 42, 84.

Solution: The factors of 84 are 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, 84, and there are 12 factors in total. Where:

Prime numbers are: 2, 3, 7

The composite numbers are: 4, 6, 12, 14, 21, 28, 42, 84

The full factors of 84 are (1,2,3,4,6,7,12,14,21,28,42,84).

12 in total.

The factors of 84 are: 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, 84.

The way to find all the factors of a number: to decompose the prime factors.

For example, the prime factor of 12 is: 2, 2, 3, then the factor of 12 is 1, 2, 3, 4, 6, 12. Correspondence method, find pairing, such as 12 = 1 12 = 2 6 = 3 4, so all the factors of 12 have .

The relationship between factors and multiples:

Factors and multiples are relative. An integer can be divisible by another integer, which is a multiple of another integer. For example, 15 is divisible by 3 or 5, so 15 is a multiple of 3 and a multiple of 5.

The quotient obtained by dividing one number by another oak banquet. For example, a b = c, it is said that a is a multiple of b. For example, if a b=c, it can be said that a is c times that of b. There are infinite multiples of a number, which means that the set of multiples of a number is an infinite set.

You can't call a number a multiple alone, you can only say who is the multiple of whom.

The factors of 84 are 1, 2, 3, 4, 21, 48, 28, 84.

In fact, the factor is generally defined as an integer: let a be an integer, b be a non-zero integer, and if there is an integer q such that a=qb, then b is a factor of a, denoted as b|a。But there are also authors who do not ask for b≠0.

Illustrate. 2x6 = 12, the product of 2 and 6 is 12, so 2 and 6 are the factors of 12. 12 is a multiple of 2 and a multiple of 6.

3x(-9) = -27, and both 3 and -9 are factors of -27. -27 is a multiple of 3 and -9.

Generally speaking, multiply the integer a by the integer b to get the integer c, and both the integer a and the integer b are called the factors of the integer c, and conversely, the integer c is a multiple of the integer a and a multiple of the integer b.

84 is a positive integer auspicious, and its factor refers to a positive integer that is divisible by 84.

The factors of 84 include , and 84 itself, for a total of 12 factors.

These factors can be obtained by enumerating the integers 1 to 84 and judging whether they are the factors of 84. It is also possible to obtain all the factors by decomposing the 84 prime factors, as follows:

First, 84 is factored into prime factors:

Then, according to the definition of a factor, the factor of a positive integer can be regarded as the product of the factor in its prime factor decomposition formula that is not greater than the factor corresponding to the prime factor exponent. Therefore, the factor of 84 comprises:

and their product. Therefore, all the factors of 84 are:

and 84 itself, a total of 12 factors.

84 of the due to the rise of the number of limbs in the calendar has a total of 3 * 2 * 2 = 12, respectively:

The factors of 84 = 2 2 3 7 84 have a total of Suifan 3*2*2=12, which are: 1, Jingchun 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, 84 Hello classmates, please click on the Liang family to comment or I wish you progress in your studies in the new semester!

The prime factor of 84 is .

In number theory, it refers to a given positive integer that is divisible.

The prime number is called the prime factor, also known as the prime factor.

Or the quality factor. Except for 1, two positive integers have no other prime factor in common, so the two positive integers are said to be cogenetic.

Decompose 84 by decomposing the prime factor, and you can get 84=2*2*3*7, so the prime factor of 84 has 2, and let .

The factors of 84 are: 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, 84

The factors of 48 are: 1, 2, 3, 4, 6, 8, 12, 24, 48

The common causes of 84 and 48 are: 1, 2, 3, 4, 6, 12
