How do I find the factor combinations of the number 555,344,140?

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 555,344,140, 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.

1 555,344,140
-1 -555,344,140

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 555,344,140.

Example:
1 x 555,344,140 = 555,344,140
and
-1 x -555,344,140 = 555,344,140
Notice both answers equal 555,344,140

With that explanation out of the way, let's continue. Next, we take the number 555,344,140 and divide it by 2:

555,344,140 ÷ 2 = 277,672,070

If the quotient is a whole number, then 2 and 277,672,070 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 2 277,672,070 555,344,140
-1 -2 -277,672,070 -555,344,140

Now, we try dividing 555,344,140 by 3:

555,344,140 ÷ 3 = 185,114,713.3333

If the quotient is a whole number, then 3 and 185,114,713.3333 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.

Here is what our table should look like at this step:

1 2 277,672,070 555,344,140
-1 -2 -277,672,070 -555,344,140

Let's try dividing by 4:

555,344,140 ÷ 4 = 138,836,035

If the quotient is a whole number, then 4 and 138,836,035 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 4 138,836,035 277,672,070 555,344,140
-1 -2 -4 -138,836,035 -277,672,070 555,344,140
Keep dividing by the next highest number until you cannot divide anymore.

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