How do I find the factor combinations of the number 11,947,896?

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 11,947,896, 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 11,947,896
-1 -11,947,896

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 11,947,896.

Example:
1 x 11,947,896 = 11,947,896
and
-1 x -11,947,896 = 11,947,896
Notice both answers equal 11,947,896

With that explanation out of the way, let's continue. Next, we take the number 11,947,896 and divide it by 2:

11,947,896 ÷ 2 = 5,973,948

If the quotient is a whole number, then 2 and 5,973,948 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 5,973,948 11,947,896
-1 -2 -5,973,948 -11,947,896

Now, we try dividing 11,947,896 by 3:

11,947,896 ÷ 3 = 3,982,632

If the quotient is a whole number, then 3 and 3,982,632 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 3,982,632 5,973,948 11,947,896
-1 -2 -3 -3,982,632 -5,973,948 -11,947,896

Let's try dividing by 4:

11,947,896 ÷ 4 = 2,986,974

If the quotient is a whole number, then 4 and 2,986,974 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 2,986,974 3,982,632 5,973,948 11,947,896
-1 -2 -3 -4 -2,986,974 -3,982,632 -5,973,948 11,947,896
Keep dividing by the next highest number until you cannot divide anymore.

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