How do I find the factor combinations of the number 27,255,582?

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 27,255,582, 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 27,255,582
-1 -27,255,582

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 27,255,582.

Example:
1 x 27,255,582 = 27,255,582
and
-1 x -27,255,582 = 27,255,582
Notice both answers equal 27,255,582

With that explanation out of the way, let's continue. Next, we take the number 27,255,582 and divide it by 2:

27,255,582 ÷ 2 = 13,627,791

If the quotient is a whole number, then 2 and 13,627,791 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 13,627,791 27,255,582
-1 -2 -13,627,791 -27,255,582

Now, we try dividing 27,255,582 by 3:

27,255,582 ÷ 3 = 9,085,194

If the quotient is a whole number, then 3 and 9,085,194 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 9,085,194 13,627,791 27,255,582
-1 -2 -3 -9,085,194 -13,627,791 -27,255,582

Let's try dividing by 4:

27,255,582 ÷ 4 = 6,813,895.5

If the quotient is a whole number, then 4 and 6,813,895.5 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 2 3 9,085,194 13,627,791 27,255,582
-1 -2 -3 -9,085,194 -13,627,791 27,255,582
Keep dividing by the next highest number until you cannot divide anymore.

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