How do I find the factor combinations of the number 726,274,411?

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 726,274,411, 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.

1 726,274,411
-1 -726,274,411

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 726,274,411.

Example:
1 x 726,274,411 = 726,274,411
and
-1 x -726,274,411 = 726,274,411
Notice both answers equal 726,274,411

With that explanation out of the way, let's continue. Next, we take the number 726,274,411 and divide it by 2:

726,274,411 ÷ 2 = 363,137,205.5

If the quotient is a whole number, then 2 and 363,137,205.5 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:

1 726,274,411
-1 -726,274,411

Now, we try dividing 726,274,411 by 3:

726,274,411 ÷ 3 = 242,091,470.3333

If the quotient is a whole number, then 3 and 242,091,470.3333 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:

1 726,274,411
-1 -726,274,411

Let's try dividing by 4:

726,274,411 ÷ 4 = 181,568,602.75

If the quotient is a whole number, then 4 and 181,568,602.75 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:

1 726,274,411
-1 726,274,411
Keep dividing by the next highest number until you cannot divide anymore.

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

11966112,55957,8291,098,75138,224,969726,274,411
-1-19-661-12,559-57,829-1,098,751-38,224,969-726,274,411
