How do I find the factor combinations of the number 181,716?

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 181,716, 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.

1 181,716
-1 -181,716

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 181,716.

Example:
1 x 181,716 = 181,716
and
-1 x -181,716 = 181,716
Notice both answers equal 181,716

With that explanation out of the way, let's continue. Next, we take the number 181,716 and divide it by 2:

181,716 ÷ 2 = 90,858

If the quotient is a whole number, then 2 and 90,858 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 90,858 181,716
-1 -2 -90,858 -181,716

Now, we try dividing 181,716 by 3:

181,716 ÷ 3 = 60,572

If the quotient is a whole number, then 3 and 60,572 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 60,572 90,858 181,716
-1 -2 -3 -60,572 -90,858 -181,716

Let's try dividing by 4:

181,716 ÷ 4 = 45,429

If the quotient is a whole number, then 4 and 45,429 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 45,429 60,572 90,858 181,716
-1 -2 -3 -4 -45,429 -60,572 -90,858 181,716
Keep dividing by the next highest number until you cannot divide anymore.

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