How do I find the factor combinations of the number 31,276,476?

Unfortunately, there's not simple formula to identifying all of the factors of a number and it can be a tedious process when trying to identify the divisors of larger numbers. To find the factor combinations of the number 31,276,476, it is easier to work with a table - it's called factoring from the outside in.

Outside in Factoring

We start by creating a table and writing 1 on the left side and then the number we're trying to find the factors for on the right side in a table. Then, below that, write the numbers as a negative as well.

1 31,276,476
-1 -31,276,476

Why are the negative numbers included?

When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 31,276,476.

Example:
1 x 31,276,476 = 31,276,476
and
-1 x -31,276,476 = 31,276,476
Notice both answers equal 31,276,476

With that explanation out of the way, let's continue. Next, we take the number 31,276,476 and divide it by 2:

31,276,476 ÷ 2 = 15,638,238

If the quotient is a whole number, then 2 and 15,638,238 are factors. In this case, the quotient is a whole number. Write them in the table inside the other two factors like the below example. Don't forget to write the negative numbers too!

Here is what our table should look like at this step:

1 2 15,638,238 31,276,476
-1 -2 -15,638,238 -31,276,476

Now, we try dividing 31,276,476 by 3:

31,276,476 ÷ 3 = 10,425,492

If the quotient is a whole number, then 3 and 10,425,492 are factors. In this case, the quotient is a whole number. Write them in the table inside the other two factors like the below example. Don't forget to write the negative numbers too!

Here is what our table should look like at this step:

1 2 3 10,425,492 15,638,238 31,276,476
-1 -2 -3 -10,425,492 -15,638,238 -31,276,476

Let's try dividing by 4:

31,276,476 ÷ 4 = 7,819,119

If the quotient is a whole number, then 4 and 7,819,119 are factors. In this case, the quotient is a whole number. Write them in the table inside the other two factors like the below example. Don't forget to write the negative numbers too!

Here is what our table should look like at this step:

1 2 3 4 7,819,119 10,425,492 15,638,238 31,276,476
-1 -2 -3 -4 -7,819,119 -10,425,492 -15,638,238 31,276,476
Keep dividing by the next highest number until you cannot divide anymore.

If you did it right, you will end up with this table:
