Q: What are the factor combinations of the number 231,192?

How do I find the factor combinations of the number 231,192?

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 231,192, 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		231,192
-1		-231,192

With that explanation out of the way, let's continue. Next, we take the number 231,192 and divide it by 2:

231,192 ÷ 2 = 115,596

If the quotient is a whole number, then 2 and 115,596 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 231,192 by 3:

231,192 ÷ 3 = 77,064

If the quotient is a whole number, then 3 and 77,064 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:

231,192 ÷ 4 = 57,798

If the quotient is a whole number, then 4 and 57,798 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:
