How do I find the factor combinations of the number 518,760?

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 518,760, 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.

1 518,760
-1 -518,760

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 518,760.

Example:
1 x 518,760 = 518,760
and
-1 x -518,760 = 518,760
Notice both answers equal 518,760

With that explanation out of the way, let's continue. Next, we take the number 518,760 and divide it by 2:

518,760 ÷ 2 = 259,380

If the quotient is a whole number, then 2 and 259,380 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 2 259,380 518,760
-1 -2 -259,380 -518,760

Now, we try dividing 518,760 by 3:

518,760 ÷ 3 = 172,920

If the quotient is a whole number, then 3 and 172,920 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 3 172,920 259,380 518,760
-1 -2 -3 -172,920 -259,380 -518,760

Let's try dividing by 4:

518,760 ÷ 4 = 129,690

If the quotient is a whole number, then 4 and 129,690 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 4 129,690 172,920 259,380 518,760
-1 -2 -3 -4 -129,690 -172,920 -259,380 518,760
Keep dividing by the next highest number until you cannot divide anymore.

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