How do I find the factor combinations of the number 13,904,359?

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 13,904,359, 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 13,904,359
-1 -13,904,359

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 13,904,359.

Example:
1 x 13,904,359 = 13,904,359
and
-1 x -13,904,359 = 13,904,359
Notice both answers equal 13,904,359

With that explanation out of the way, let's continue. Next, we take the number 13,904,359 and divide it by 2:

13,904,359 ÷ 2 = 6,952,179.5

If the quotient is a whole number, then 2 and 6,952,179.5 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 13,904,359
-1 -13,904,359

Now, we try dividing 13,904,359 by 3:

13,904,359 ÷ 3 = 4,634,786.3333

If the quotient is a whole number, then 3 and 4,634,786.3333 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 13,904,359
-1 -13,904,359

Let's try dividing by 4:

13,904,359 ÷ 4 = 3,476,089.75

If the quotient is a whole number, then 4 and 3,476,089.75 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 13,904,359
-1 13,904,359
Keep dividing by the next highest number until you cannot divide anymore.

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

171,986,33713,904,359
-1-7-1,986,337-13,904,359
