How do I find the factor combinations of the number 81,322,500?

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 81,322,500, 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 81,322,500
-1 -81,322,500

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 81,322,500.

Example:
1 x 81,322,500 = 81,322,500
and
-1 x -81,322,500 = 81,322,500
Notice both answers equal 81,322,500

With that explanation out of the way, let's continue. Next, we take the number 81,322,500 and divide it by 2:

81,322,500 ÷ 2 = 40,661,250

If the quotient is a whole number, then 2 and 40,661,250 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 40,661,250 81,322,500
-1 -2 -40,661,250 -81,322,500

Now, we try dividing 81,322,500 by 3:

81,322,500 ÷ 3 = 27,107,500

If the quotient is a whole number, then 3 and 27,107,500 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 27,107,500 40,661,250 81,322,500
-1 -2 -3 -27,107,500 -40,661,250 -81,322,500

Let's try dividing by 4:

81,322,500 ÷ 4 = 20,330,625

If the quotient is a whole number, then 4 and 20,330,625 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 20,330,625 27,107,500 40,661,250 81,322,500
-1 -2 -3 -4 -20,330,625 -27,107,500 -40,661,250 81,322,500
Keep dividing by the next highest number until you cannot divide anymore.

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