How do I find the factor combinations of the number 23,121,336?

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 23,121,336, 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 23,121,336
-1 -23,121,336

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 23,121,336.

Example:
1 x 23,121,336 = 23,121,336
and
-1 x -23,121,336 = 23,121,336
Notice both answers equal 23,121,336

With that explanation out of the way, let's continue. Next, we take the number 23,121,336 and divide it by 2:

23,121,336 ÷ 2 = 11,560,668

If the quotient is a whole number, then 2 and 11,560,668 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 11,560,668 23,121,336
-1 -2 -11,560,668 -23,121,336

Now, we try dividing 23,121,336 by 3:

23,121,336 ÷ 3 = 7,707,112

If the quotient is a whole number, then 3 and 7,707,112 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 7,707,112 11,560,668 23,121,336
-1 -2 -3 -7,707,112 -11,560,668 -23,121,336

Let's try dividing by 4:

23,121,336 ÷ 4 = 5,780,334

If the quotient is a whole number, then 4 and 5,780,334 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 5,780,334 7,707,112 11,560,668 23,121,336
-1 -2 -3 -4 -5,780,334 -7,707,112 -11,560,668 23,121,336
Keep dividing by the next highest number until you cannot divide anymore.

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