How do I find the factor combinations of the number 99,490,314?

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 99,490,314, 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 99,490,314
-1 -99,490,314

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 99,490,314.

Example:
1 x 99,490,314 = 99,490,314
and
-1 x -99,490,314 = 99,490,314
Notice both answers equal 99,490,314

With that explanation out of the way, let's continue. Next, we take the number 99,490,314 and divide it by 2:

99,490,314 ÷ 2 = 49,745,157

If the quotient is a whole number, then 2 and 49,745,157 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 49,745,157 99,490,314
-1 -2 -49,745,157 -99,490,314

Now, we try dividing 99,490,314 by 3:

99,490,314 ÷ 3 = 33,163,438

If the quotient is a whole number, then 3 and 33,163,438 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 33,163,438 49,745,157 99,490,314
-1 -2 -3 -33,163,438 -49,745,157 -99,490,314

Let's try dividing by 4:

99,490,314 ÷ 4 = 24,872,578.5

If the quotient is a whole number, then 4 and 24,872,578.5 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 33,163,438 49,745,157 99,490,314
-1 -2 -3 -33,163,438 -49,745,157 99,490,314
Keep dividing by the next highest number until you cannot divide anymore.

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