How do I find the factor combinations of the number 20,669,484?

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 20,669,484, 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 20,669,484
-1 -20,669,484

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 20,669,484.

Example:
1 x 20,669,484 = 20,669,484
and
-1 x -20,669,484 = 20,669,484
Notice both answers equal 20,669,484

With that explanation out of the way, let's continue. Next, we take the number 20,669,484 and divide it by 2:

20,669,484 ÷ 2 = 10,334,742

If the quotient is a whole number, then 2 and 10,334,742 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 10,334,742 20,669,484
-1 -2 -10,334,742 -20,669,484

Now, we try dividing 20,669,484 by 3:

20,669,484 ÷ 3 = 6,889,828

If the quotient is a whole number, then 3 and 6,889,828 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 6,889,828 10,334,742 20,669,484
-1 -2 -3 -6,889,828 -10,334,742 -20,669,484

Let's try dividing by 4:

20,669,484 ÷ 4 = 5,167,371

If the quotient is a whole number, then 4 and 5,167,371 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 5,167,371 6,889,828 10,334,742 20,669,484
-1 -2 -3 -4 -5,167,371 -6,889,828 -10,334,742 20,669,484
Keep dividing by the next highest number until you cannot divide anymore.

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