How do I find the factor combinations of the number 615,720,060?

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 615,720,060, 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.

1 615,720,060
-1 -615,720,060

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 615,720,060.

Example:
1 x 615,720,060 = 615,720,060
and
-1 x -615,720,060 = 615,720,060
Notice both answers equal 615,720,060

With that explanation out of the way, let's continue. Next, we take the number 615,720,060 and divide it by 2:

615,720,060 ÷ 2 = 307,860,030

If the quotient is a whole number, then 2 and 307,860,030 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 2 307,860,030 615,720,060
-1 -2 -307,860,030 -615,720,060

Now, we try dividing 615,720,060 by 3:

615,720,060 ÷ 3 = 205,240,020

If the quotient is a whole number, then 3 and 205,240,020 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 3 205,240,020 307,860,030 615,720,060
-1 -2 -3 -205,240,020 -307,860,030 -615,720,060

Let's try dividing by 4:

615,720,060 ÷ 4 = 153,930,015

If the quotient is a whole number, then 4 and 153,930,015 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 4 153,930,015 205,240,020 307,860,030 615,720,060
-1 -2 -3 -4 -153,930,015 -205,240,020 -307,860,030 615,720,060
Keep dividing by the next highest number until you cannot divide anymore.

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