# What are all the factors, the prime factorization, and factor pairs of 972?

To find the factors of 972, divide 972 by each number starting with 1 and working up to 972

## What is a factor in math ?

Factors are the numbers you multiply together to get another number. For example, the factors of 15 are 3 and 5 because 3 × 5 = 15.

The factors of a number can be positive or negative, but they cannot be zero.

The factors of a number can be used to find out if the number is prime or not.

A prime number is a number that has only two factors: itself and 1. For example, the number 7 is prime because its only factors are 7 and 1.

## List all of the factors of 972 ?

To calculate the factors of 972 , you can use the division method.

1. Begin by dividing 972 by the smallest possible number, which is 2.

2. If the division is even, then 2 is a factor of 972.

3. Continue dividing 972 by larger numbers until you find an odd number that does not divide evenly into 972 .

4. The numbers that divide evenly into 972 are the factors of 972 .

Now let us find how to calculate all the factors of Nine hundred seventy-two :

972 ÷ 1 = 972
972 ÷ 2 = 486
972 ÷ 3 = 324
972 ÷ 4 = 243
972 ÷ 6 = 162
972 ÷ 9 = 108
972 ÷ 12 = 81
972 ÷ 18 = 54
972 ÷ 27 = 36
972 ÷ 36 = 27
972 ÷ 54 = 18
972 ÷ 81 = 12
972 ÷ 108 = 9
972 ÷ 162 = 6
972 ÷ 243 = 4
972 ÷ 324 = 3
972 ÷ 486 = 2
972 ÷ 972 = 1

As you can see, the factors of 972 are 1 , 2 , 3 , 4 , 6 , 9 , 12 , 18 , 27 , 36 , 54 , 81 , 108 , 162 , 243 , 324 , 486 and 972 .

## How many factors of 972 are there ?

The factors of 972 are the numbers that can evenly divide 972 . These numbers are 1 , 2 , 3 , 4 , 6 , 9 , 12 , 18 , 27 , 36 , 54 , 81 , 108 , 162 , 243 , 324 , 486 and 972.

Thus, there are a total of 18 factors of 972

## What are the factor pairs of 972 ?

Factor Pairs of 972 are combinations of two factors that when multiplied together equal 972. There are many ways to calculate the factor pairs of 972 .

One easy way is to list out the factors of 972 :
1 , 2 , 3 , 4 , 6 , 9 , 12 , 18 , 27 , 36 , 54 , 81 , 108 , 162 , 243 , 324 , 486 , 972

Then, pair up the factors:
(1,972),(2,486),(3,324),(4,243),(6,162),(9,108),(12,81),(18,54) and (27,36) These are the factor pairs of 972 .

## Prime Factorisation of 972

There are a few different methods that can be used to calculate the prime factorization of a number. Two of the most common methods are listed below.

1) Use a factor tree :

1. Take the number you want to find the prime factorization of and write it at the top of the page

2. Find the smallest number that goes into the number you are finding the prime factorization of evenly and write it next to the number you are finding the prime factorization of

3. Draw a line under the number you just wrote and the number you are finding the prime factorization of

4. Repeat step 2 with the number you just wrote until that number can no longer be divided evenly

5. The numbers written on the lines will be the prime factors of the number you started with

For example, to calculate the prime factorization of 972 using a factor tree, we would start by writing 972 on a piece of paper. Then, we would draw a line under it and begin finding factors.

The final prime factorization of 972 would be 2 x 2 x 3 x 3 x 3 x 3 x 3.

2) Use a factorization method :

There are a few different factorization methods that can be used to calculate the prime factorization of a number.

One common method is to start by dividing the number by the smallest prime number that will divide evenly into it.

Then, continue dividing the number by successively larger prime numbers until the number has been fully factorised.

For example, to calculate the prime factorization of 972 using this method, we keep dividing until it gives a non-zero remainder.

972 ÷ 2 = 486
486 ÷ 2 = 243
243 ÷ 3 = 81
81 ÷ 3 = 27
27 ÷ 3 = 9
9 ÷ 3 = 3
3 ÷ 3 = 1

So the prime factors of 972 are 2 x 2 x 3 x 3 x 3 x 3 x 3.
