How do I find the factor combinations of the number 18,544,632?

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 18,544,632, 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 18,544,632
-1 -18,544,632

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 18,544,632.

Example:
1 x 18,544,632 = 18,544,632
and
-1 x -18,544,632 = 18,544,632
Notice both answers equal 18,544,632

With that explanation out of the way, let's continue. Next, we take the number 18,544,632 and divide it by 2:

18,544,632 ÷ 2 = 9,272,316

If the quotient is a whole number, then 2 and 9,272,316 are factors. In this case, the quotient is a whole number. Write them in the table inside the other two factors like the below example. Don't forget to write the negative numbers too!

Here is what our table should look like at this step:

1 2 9,272,316 18,544,632
-1 -2 -9,272,316 -18,544,632

Now, we try dividing 18,544,632 by 3:

18,544,632 ÷ 3 = 6,181,544

If the quotient is a whole number, then 3 and 6,181,544 are factors. In this case, the quotient is a whole number. Write them in the table inside the other two factors like the below example. Don't forget to write the negative numbers too!

Here is what our table should look like at this step:

1 2 3 6,181,544 9,272,316 18,544,632
-1 -2 -3 -6,181,544 -9,272,316 -18,544,632

Let's try dividing by 4:

18,544,632 ÷ 4 = 4,636,158

If the quotient is a whole number, then 4 and 4,636,158 are factors. In this case, the quotient is a whole number. Write them in the table inside the other two factors like the below example. Don't forget to write the negative numbers too!

Here is what our table should look like at this step:

1 2 3 4 4,636,158 6,181,544 9,272,316 18,544,632
-1 -2 -3 -4 -4,636,158 -6,181,544 -9,272,316 18,544,632
Keep dividing by the next highest number until you cannot divide anymore.

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