How do I find the factor combinations of the number 351,451,344?

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 351,451,344, 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.

1 351,451,344
-1 -351,451,344

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 351,451,344.

Example:
1 x 351,451,344 = 351,451,344
and
-1 x -351,451,344 = 351,451,344
Notice both answers equal 351,451,344

With that explanation out of the way, let's continue. Next, we take the number 351,451,344 and divide it by 2:

351,451,344 ÷ 2 = 175,725,672

If the quotient is a whole number, then 2 and 175,725,672 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 2 175,725,672 351,451,344
-1 -2 -175,725,672 -351,451,344

Now, we try dividing 351,451,344 by 3:

351,451,344 ÷ 3 = 117,150,448

If the quotient is a whole number, then 3 and 117,150,448 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 3 117,150,448 175,725,672 351,451,344
-1 -2 -3 -117,150,448 -175,725,672 -351,451,344

Let's try dividing by 4:

351,451,344 ÷ 4 = 87,862,836

If the quotient is a whole number, then 4 and 87,862,836 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 87,862,836 117,150,448 175,725,672 351,451,344
-1 -2 -3 -4 -87,862,836 -117,150,448 -175,725,672 351,451,344
Keep dividing by the next highest number until you cannot divide anymore.

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