How do I find the factor combinations of the number 320,211,324?

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 320,211,324, 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.

1 320,211,324
-1 -320,211,324

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 320,211,324.

Example:
1 x 320,211,324 = 320,211,324
and
-1 x -320,211,324 = 320,211,324
Notice both answers equal 320,211,324

With that explanation out of the way, let's continue. Next, we take the number 320,211,324 and divide it by 2:

320,211,324 ÷ 2 = 160,105,662

If the quotient is a whole number, then 2 and 160,105,662 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 2 160,105,662 320,211,324
-1 -2 -160,105,662 -320,211,324

Now, we try dividing 320,211,324 by 3:

320,211,324 ÷ 3 = 106,737,108

If the quotient is a whole number, then 3 and 106,737,108 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 3 106,737,108 160,105,662 320,211,324
-1 -2 -3 -106,737,108 -160,105,662 -320,211,324

Let's try dividing by 4:

320,211,324 ÷ 4 = 80,052,831

If the quotient is a whole number, then 4 and 80,052,831 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 80,052,831 106,737,108 160,105,662 320,211,324
-1 -2 -3 -4 -80,052,831 -106,737,108 -160,105,662 320,211,324
Keep dividing by the next highest number until you cannot divide anymore.

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