How do I find the factor combinations of the number 125,518,308?

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 125,518,308, 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.

1 125,518,308
-1 -125,518,308

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 125,518,308.

Example:
1 x 125,518,308 = 125,518,308
and
-1 x -125,518,308 = 125,518,308
Notice both answers equal 125,518,308

With that explanation out of the way, let's continue. Next, we take the number 125,518,308 and divide it by 2:

125,518,308 ÷ 2 = 62,759,154

If the quotient is a whole number, then 2 and 62,759,154 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 62,759,154 125,518,308
-1 -2 -62,759,154 -125,518,308

Now, we try dividing 125,518,308 by 3:

125,518,308 ÷ 3 = 41,839,436

If the quotient is a whole number, then 3 and 41,839,436 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 41,839,436 62,759,154 125,518,308
-1 -2 -3 -41,839,436 -62,759,154 -125,518,308

Let's try dividing by 4:

125,518,308 ÷ 4 = 31,379,577

If the quotient is a whole number, then 4 and 31,379,577 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 31,379,577 41,839,436 62,759,154 125,518,308
-1 -2 -3 -4 -31,379,577 -41,839,436 -62,759,154 125,518,308
Keep dividing by the next highest number until you cannot divide anymore.

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

123461210,459,85920,919,71831,379,57741,839,43662,759,154125,518,308
