How do I find the factor combinations of the number 81,777,228?

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 81,777,228, 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 81,777,228
-1 -81,777,228

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 81,777,228.

Example:
1 x 81,777,228 = 81,777,228
and
-1 x -81,777,228 = 81,777,228
Notice both answers equal 81,777,228

With that explanation out of the way, let's continue. Next, we take the number 81,777,228 and divide it by 2:

81,777,228 ÷ 2 = 40,888,614

If the quotient is a whole number, then 2 and 40,888,614 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 40,888,614 81,777,228
-1 -2 -40,888,614 -81,777,228

Now, we try dividing 81,777,228 by 3:

81,777,228 ÷ 3 = 27,259,076

If the quotient is a whole number, then 3 and 27,259,076 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 27,259,076 40,888,614 81,777,228
-1 -2 -3 -27,259,076 -40,888,614 -81,777,228

Let's try dividing by 4:

81,777,228 ÷ 4 = 20,444,307

If the quotient is a whole number, then 4 and 20,444,307 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 20,444,307 27,259,076 40,888,614 81,777,228
-1 -2 -3 -4 -20,444,307 -27,259,076 -40,888,614 81,777,228
Keep dividing by the next highest number until you cannot divide anymore.

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