How do I find the factor combinations of the number 320,110,308?

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 320,110,308, 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.

1 320,110,308
-1 -320,110,308

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 320,110,308.

Example:
1 x 320,110,308 = 320,110,308
and
-1 x -320,110,308 = 320,110,308
Notice both answers equal 320,110,308

With that explanation out of the way, let's continue. Next, we take the number 320,110,308 and divide it by 2:

320,110,308 ÷ 2 = 160,055,154

If the quotient is a whole number, then 2 and 160,055,154 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 2 160,055,154 320,110,308
-1 -2 -160,055,154 -320,110,308

Now, we try dividing 320,110,308 by 3:

320,110,308 ÷ 3 = 106,703,436

If the quotient is a whole number, then 3 and 106,703,436 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 3 106,703,436 160,055,154 320,110,308
-1 -2 -3 -106,703,436 -160,055,154 -320,110,308

Let's try dividing by 4:

320,110,308 ÷ 4 = 80,027,577

If the quotient is a whole number, then 4 and 80,027,577 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 80,027,577 106,703,436 160,055,154 320,110,308
-1 -2 -3 -4 -80,027,577 -106,703,436 -160,055,154 320,110,308
Keep dividing by the next highest number until you cannot divide anymore.

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