How do I find the factor combinations of the number 331,507,584?

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 331,507,584, 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.

1 331,507,584
-1 -331,507,584

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 331,507,584.

Example:
1 x 331,507,584 = 331,507,584
and
-1 x -331,507,584 = 331,507,584
Notice both answers equal 331,507,584

With that explanation out of the way, let's continue. Next, we take the number 331,507,584 and divide it by 2:

331,507,584 ÷ 2 = 165,753,792

If the quotient is a whole number, then 2 and 165,753,792 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 2 165,753,792 331,507,584
-1 -2 -165,753,792 -331,507,584

Now, we try dividing 331,507,584 by 3:

331,507,584 ÷ 3 = 110,502,528

If the quotient is a whole number, then 3 and 110,502,528 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 3 110,502,528 165,753,792 331,507,584
-1 -2 -3 -110,502,528 -165,753,792 -331,507,584

Let's try dividing by 4:

331,507,584 ÷ 4 = 82,876,896

If the quotient is a whole number, then 4 and 82,876,896 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 82,876,896 110,502,528 165,753,792 331,507,584
-1 -2 -3 -4 -82,876,896 -110,502,528 -165,753,792 331,507,584
Keep dividing by the next highest number until you cannot divide anymore.

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