How do I find the factor combinations of the number 431,356,122?

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 431,356,122, 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.

1 431,356,122
-1 -431,356,122

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 431,356,122.

Example:
1 x 431,356,122 = 431,356,122
and
-1 x -431,356,122 = 431,356,122
Notice both answers equal 431,356,122

With that explanation out of the way, let's continue. Next, we take the number 431,356,122 and divide it by 2:

431,356,122 ÷ 2 = 215,678,061

If the quotient is a whole number, then 2 and 215,678,061 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 2 215,678,061 431,356,122
-1 -2 -215,678,061 -431,356,122

Now, we try dividing 431,356,122 by 3:

431,356,122 ÷ 3 = 143,785,374

If the quotient is a whole number, then 3 and 143,785,374 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 3 143,785,374 215,678,061 431,356,122
-1 -2 -3 -143,785,374 -215,678,061 -431,356,122

Let's try dividing by 4:

431,356,122 ÷ 4 = 107,839,030.5

If the quotient is a whole number, then 4 and 107,839,030.5 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 3 143,785,374 215,678,061 431,356,122
-1 -2 -3 -143,785,374 -215,678,061 431,356,122
Keep dividing by the next highest number until you cannot divide anymore.

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