How do I find the factor combinations of the number 725,758,188?

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 725,758,188, 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.

1 725,758,188
-1 -725,758,188

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 725,758,188.

Example:
1 x 725,758,188 = 725,758,188
and
-1 x -725,758,188 = 725,758,188
Notice both answers equal 725,758,188

With that explanation out of the way, let's continue. Next, we take the number 725,758,188 and divide it by 2:

725,758,188 ÷ 2 = 362,879,094

If the quotient is a whole number, then 2 and 362,879,094 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 2 362,879,094 725,758,188
-1 -2 -362,879,094 -725,758,188

Now, we try dividing 725,758,188 by 3:

725,758,188 ÷ 3 = 241,919,396

If the quotient is a whole number, then 3 and 241,919,396 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 3 241,919,396 362,879,094 725,758,188
-1 -2 -3 -241,919,396 -362,879,094 -725,758,188

Let's try dividing by 4:

725,758,188 ÷ 4 = 181,439,547

If the quotient is a whole number, then 4 and 181,439,547 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 4 181,439,547 241,919,396 362,879,094 725,758,188
-1 -2 -3 -4 -181,439,547 -241,919,396 -362,879,094 725,758,188
Keep dividing by the next highest number until you cannot divide anymore.

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