How do I find the factor combinations of the number 173,266,613?

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 173,266,613, 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.

1 173,266,613
-1 -173,266,613

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 173,266,613.

Example:
1 x 173,266,613 = 173,266,613
and
-1 x -173,266,613 = 173,266,613
Notice both answers equal 173,266,613

With that explanation out of the way, let's continue. Next, we take the number 173,266,613 and divide it by 2:

173,266,613 ÷ 2 = 86,633,306.5

If the quotient is a whole number, then 2 and 86,633,306.5 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:

1 173,266,613
-1 -173,266,613

Now, we try dividing 173,266,613 by 3:

173,266,613 ÷ 3 = 57,755,537.6667

If the quotient is a whole number, then 3 and 57,755,537.6667 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:

1 173,266,613
-1 -173,266,613

Let's try dividing by 4:

173,266,613 ÷ 4 = 43,316,653.25

If the quotient is a whole number, then 4 and 43,316,653.25 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:

1 173,266,613
-1 173,266,613
Keep dividing by the next highest number until you cannot divide anymore.

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