How do I find the factor combinations of the number 15,447,348?

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 15,447,348, 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 15,447,348
-1 -15,447,348

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 15,447,348.

Example:
1 x 15,447,348 = 15,447,348
and
-1 x -15,447,348 = 15,447,348
Notice both answers equal 15,447,348

With that explanation out of the way, let's continue. Next, we take the number 15,447,348 and divide it by 2:

15,447,348 ÷ 2 = 7,723,674

If the quotient is a whole number, then 2 and 7,723,674 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 7,723,674 15,447,348
-1 -2 -7,723,674 -15,447,348

Now, we try dividing 15,447,348 by 3:

15,447,348 ÷ 3 = 5,149,116

If the quotient is a whole number, then 3 and 5,149,116 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 5,149,116 7,723,674 15,447,348
-1 -2 -3 -5,149,116 -7,723,674 -15,447,348

Let's try dividing by 4:

15,447,348 ÷ 4 = 3,861,837

If the quotient is a whole number, then 4 and 3,861,837 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 3,861,837 5,149,116 7,723,674 15,447,348
-1 -2 -3 -4 -3,861,837 -5,149,116 -7,723,674 15,447,348
Keep dividing by the next highest number until you cannot divide anymore.

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