How do I find the factor combinations of the number 19,941,912?

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 19,941,912, 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 19,941,912
-1 -19,941,912

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 19,941,912.

Example:
1 x 19,941,912 = 19,941,912
and
-1 x -19,941,912 = 19,941,912
Notice both answers equal 19,941,912

With that explanation out of the way, let's continue. Next, we take the number 19,941,912 and divide it by 2:

19,941,912 ÷ 2 = 9,970,956

If the quotient is a whole number, then 2 and 9,970,956 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 9,970,956 19,941,912
-1 -2 -9,970,956 -19,941,912

Now, we try dividing 19,941,912 by 3:

19,941,912 ÷ 3 = 6,647,304

If the quotient is a whole number, then 3 and 6,647,304 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 6,647,304 9,970,956 19,941,912
-1 -2 -3 -6,647,304 -9,970,956 -19,941,912

Let's try dividing by 4:

19,941,912 ÷ 4 = 4,985,478

If the quotient is a whole number, then 4 and 4,985,478 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 4,985,478 6,647,304 9,970,956 19,941,912
-1 -2 -3 -4 -4,985,478 -6,647,304 -9,970,956 19,941,912
Keep dividing by the next highest number until you cannot divide anymore.

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