How do I find the factor combinations of the number 18,260,539?

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 18,260,539, 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 18,260,539
-1 -18,260,539

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 18,260,539.

Example:
1 x 18,260,539 = 18,260,539
and
-1 x -18,260,539 = 18,260,539
Notice both answers equal 18,260,539

With that explanation out of the way, let's continue. Next, we take the number 18,260,539 and divide it by 2:

18,260,539 ÷ 2 = 9,130,269.5

If the quotient is a whole number, then 2 and 9,130,269.5 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 18,260,539
-1 -18,260,539

Now, we try dividing 18,260,539 by 3:

18,260,539 ÷ 3 = 6,086,846.3333

If the quotient is a whole number, then 3 and 6,086,846.3333 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 18,260,539
-1 -18,260,539

Let's try dividing by 4:

18,260,539 ÷ 4 = 4,565,134.75

If the quotient is a whole number, then 4 and 4,565,134.75 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 18,260,539
-1 18,260,539
Keep dividing by the next highest number until you cannot divide anymore.

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