How do I find the factor combinations of the number 726,712,441?

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 726,712,441, 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.

1 726,712,441
-1 -726,712,441

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 726,712,441.

Example:
1 x 726,712,441 = 726,712,441
and
-1 x -726,712,441 = 726,712,441
Notice both answers equal 726,712,441

With that explanation out of the way, let's continue. Next, we take the number 726,712,441 and divide it by 2:

726,712,441 ÷ 2 = 363,356,220.5

If the quotient is a whole number, then 2 and 363,356,220.5 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:

1 726,712,441
-1 -726,712,441

Now, we try dividing 726,712,441 by 3:

726,712,441 ÷ 3 = 242,237,480.3333

If the quotient is a whole number, then 3 and 242,237,480.3333 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:

1 726,712,441
-1 -726,712,441

Let's try dividing by 4:

726,712,441 ÷ 4 = 181,678,110.25

If the quotient is a whole number, then 4 and 181,678,110.25 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:

1 726,712,441
-1 726,712,441
Keep dividing by the next highest number until you cannot divide anymore.

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

1713917,985,85155,900,957103,816,063726,712,441
