How do I find the factor combinations of the number 125,550,312?

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 125,550,312, 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.

1 125,550,312
-1 -125,550,312

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 125,550,312.

Example:
1 x 125,550,312 = 125,550,312
and
-1 x -125,550,312 = 125,550,312
Notice both answers equal 125,550,312

With that explanation out of the way, let's continue. Next, we take the number 125,550,312 and divide it by 2:

125,550,312 ÷ 2 = 62,775,156

If the quotient is a whole number, then 2 and 62,775,156 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 62,775,156 125,550,312
-1 -2 -62,775,156 -125,550,312

Now, we try dividing 125,550,312 by 3:

125,550,312 ÷ 3 = 41,850,104

If the quotient is a whole number, then 3 and 41,850,104 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 41,850,104 62,775,156 125,550,312
-1 -2 -3 -41,850,104 -62,775,156 -125,550,312

Let's try dividing by 4:

125,550,312 ÷ 4 = 31,387,578

If the quotient is a whole number, then 4 and 31,387,578 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 31,387,578 41,850,104 62,775,156 125,550,312
-1 -2 -3 -4 -31,387,578 -41,850,104 -62,775,156 125,550,312
Keep dividing by the next highest number until you cannot divide anymore.

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