How do I find the factor combinations of the number 326,928?

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 326,928, 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.

1 326,928
-1 -326,928

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 326,928.

Example:
1 x 326,928 = 326,928
and
-1 x -326,928 = 326,928
Notice both answers equal 326,928

With that explanation out of the way, let's continue. Next, we take the number 326,928 and divide it by 2:

326,928 ÷ 2 = 163,464

If the quotient is a whole number, then 2 and 163,464 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 2 163,464 326,928
-1 -2 -163,464 -326,928

Now, we try dividing 326,928 by 3:

326,928 ÷ 3 = 108,976

If the quotient is a whole number, then 3 and 108,976 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 3 108,976 163,464 326,928
-1 -2 -3 -108,976 -163,464 -326,928

Let's try dividing by 4:

326,928 ÷ 4 = 81,732

If the quotient is a whole number, then 4 and 81,732 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 81,732 108,976 163,464 326,928
-1 -2 -3 -4 -81,732 -108,976 -163,464 326,928
Keep dividing by the next highest number until you cannot divide anymore.

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