Q: What are the factor combinations of the number 931,728?

How do I find the factor combinations of the number 931,728?

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 931,728, 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		931,728
-1		-931,728

With that explanation out of the way, let's continue. Next, we take the number 931,728 and divide it by 2:

931,728 ÷ 2 = 465,864

If the quotient is a whole number, then 2 and 465,864 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:

Now, we try dividing 931,728 by 3:

931,728 ÷ 3 = 310,576

If the quotient is a whole number, then 3 and 310,576 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:

Let's try dividing by 4:

931,728 ÷ 4 = 232,932

If the quotient is a whole number, then 4 and 232,932 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:

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