How do I find the factor combinations of the number 20,518,176?

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 20,518,176, 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 20,518,176
-1 -20,518,176

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 20,518,176.

Example:
1 x 20,518,176 = 20,518,176
and
-1 x -20,518,176 = 20,518,176
Notice both answers equal 20,518,176

With that explanation out of the way, let's continue. Next, we take the number 20,518,176 and divide it by 2:

20,518,176 ÷ 2 = 10,259,088

If the quotient is a whole number, then 2 and 10,259,088 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 10,259,088 20,518,176
-1 -2 -10,259,088 -20,518,176

Now, we try dividing 20,518,176 by 3:

20,518,176 ÷ 3 = 6,839,392

If the quotient is a whole number, then 3 and 6,839,392 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 6,839,392 10,259,088 20,518,176
-1 -2 -3 -6,839,392 -10,259,088 -20,518,176

Let's try dividing by 4:

20,518,176 ÷ 4 = 5,129,544

If the quotient is a whole number, then 4 and 5,129,544 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 4 5,129,544 6,839,392 10,259,088 20,518,176
-1 -2 -3 -4 -5,129,544 -6,839,392 -10,259,088 20,518,176
Keep dividing by the next highest number until you cannot divide anymore.

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