How do I find the factor combinations of the number 722,151,755?

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 722,151,755, 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.

1 722,151,755
-1 -722,151,755

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 722,151,755.

Example:
1 x 722,151,755 = 722,151,755
and
-1 x -722,151,755 = 722,151,755
Notice both answers equal 722,151,755

With that explanation out of the way, let's continue. Next, we take the number 722,151,755 and divide it by 2:

722,151,755 ÷ 2 = 361,075,877.5

If the quotient is a whole number, then 2 and 361,075,877.5 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:

1 722,151,755
-1 -722,151,755

Now, we try dividing 722,151,755 by 3:

722,151,755 ÷ 3 = 240,717,251.6667

If the quotient is a whole number, then 3 and 240,717,251.6667 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:

1 722,151,755
-1 -722,151,755

Let's try dividing by 4:

722,151,755 ÷ 4 = 180,537,938.75

If the quotient is a whole number, then 4 and 180,537,938.75 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:

1 722,151,755
-1 722,151,755
Keep dividing by the next highest number until you cannot divide anymore.

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