How do I find the factor combinations of the number 180,568,380?

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 180,568,380, 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.

1 180,568,380
-1 -180,568,380

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 180,568,380.

Example:
1 x 180,568,380 = 180,568,380
and
-1 x -180,568,380 = 180,568,380
Notice both answers equal 180,568,380

With that explanation out of the way, let's continue. Next, we take the number 180,568,380 and divide it by 2:

180,568,380 ÷ 2 = 90,284,190

If the quotient is a whole number, then 2 and 90,284,190 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 90,284,190 180,568,380
-1 -2 -90,284,190 -180,568,380

Now, we try dividing 180,568,380 by 3:

180,568,380 ÷ 3 = 60,189,460

If the quotient is a whole number, then 3 and 60,189,460 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 60,189,460 90,284,190 180,568,380
-1 -2 -3 -60,189,460 -90,284,190 -180,568,380

Let's try dividing by 4:

180,568,380 ÷ 4 = 45,142,095

If the quotient is a whole number, then 4 and 45,142,095 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 45,142,095 60,189,460 90,284,190 180,568,380
-1 -2 -3 -4 -45,142,095 -60,189,460 -90,284,190 180,568,380
Keep dividing by the next highest number until you cannot divide anymore.

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