How do I find the factor combinations of the number 425,205,324?

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 425,205,324, 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.

1 425,205,324
-1 -425,205,324

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 425,205,324.

Example:
1 x 425,205,324 = 425,205,324
and
-1 x -425,205,324 = 425,205,324
Notice both answers equal 425,205,324

With that explanation out of the way, let's continue. Next, we take the number 425,205,324 and divide it by 2:

425,205,324 ÷ 2 = 212,602,662

If the quotient is a whole number, then 2 and 212,602,662 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 2 212,602,662 425,205,324
-1 -2 -212,602,662 -425,205,324

Now, we try dividing 425,205,324 by 3:

425,205,324 ÷ 3 = 141,735,108

If the quotient is a whole number, then 3 and 141,735,108 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 3 141,735,108 212,602,662 425,205,324
-1 -2 -3 -141,735,108 -212,602,662 -425,205,324

Let's try dividing by 4:

425,205,324 ÷ 4 = 106,301,331

If the quotient is a whole number, then 4 and 106,301,331 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 4 106,301,331 141,735,108 212,602,662 425,205,324
-1 -2 -3 -4 -106,301,331 -141,735,108 -212,602,662 425,205,324
Keep dividing by the next highest number until you cannot divide anymore.

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