How do I find the factor combinations of the number 231,532,416?

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 231,532,416, 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.

1 231,532,416
-1 -231,532,416

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 231,532,416.

Example:
1 x 231,532,416 = 231,532,416
and
-1 x -231,532,416 = 231,532,416
Notice both answers equal 231,532,416

With that explanation out of the way, let's continue. Next, we take the number 231,532,416 and divide it by 2:

231,532,416 ÷ 2 = 115,766,208

If the quotient is a whole number, then 2 and 115,766,208 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 2 115,766,208 231,532,416
-1 -2 -115,766,208 -231,532,416

Now, we try dividing 231,532,416 by 3:

231,532,416 ÷ 3 = 77,177,472

If the quotient is a whole number, then 3 and 77,177,472 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 77,177,472 115,766,208 231,532,416
-1 -2 -3 -77,177,472 -115,766,208 -231,532,416

Let's try dividing by 4:

231,532,416 ÷ 4 = 57,883,104

If the quotient is a whole number, then 4 and 57,883,104 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 57,883,104 77,177,472 115,766,208 231,532,416
-1 -2 -3 -4 -57,883,104 -77,177,472 -115,766,208 231,532,416
Keep dividing by the next highest number until you cannot divide anymore.

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