How do I find the factor combinations of the number 12,836,736?

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 12,836,736, 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 12,836,736
-1 -12,836,736

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 12,836,736.

Example:
1 x 12,836,736 = 12,836,736
and
-1 x -12,836,736 = 12,836,736
Notice both answers equal 12,836,736

With that explanation out of the way, let's continue. Next, we take the number 12,836,736 and divide it by 2:

12,836,736 ÷ 2 = 6,418,368

If the quotient is a whole number, then 2 and 6,418,368 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 6,418,368 12,836,736
-1 -2 -6,418,368 -12,836,736

Now, we try dividing 12,836,736 by 3:

12,836,736 ÷ 3 = 4,278,912

If the quotient is a whole number, then 3 and 4,278,912 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 4,278,912 6,418,368 12,836,736
-1 -2 -3 -4,278,912 -6,418,368 -12,836,736

Let's try dividing by 4:

12,836,736 ÷ 4 = 3,209,184

If the quotient is a whole number, then 4 and 3,209,184 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 3,209,184 4,278,912 6,418,368 12,836,736
-1 -2 -3 -4 -3,209,184 -4,278,912 -6,418,368 12,836,736
Keep dividing by the next highest number until you cannot divide anymore.

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