How do I find the factor combinations of the number 768,563,316?

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 768,563,316, 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.

1 768,563,316
-1 -768,563,316

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 768,563,316.

Example:
1 x 768,563,316 = 768,563,316
and
-1 x -768,563,316 = 768,563,316
Notice both answers equal 768,563,316

With that explanation out of the way, let's continue. Next, we take the number 768,563,316 and divide it by 2:

768,563,316 ÷ 2 = 384,281,658

If the quotient is a whole number, then 2 and 384,281,658 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 2 384,281,658 768,563,316
-1 -2 -384,281,658 -768,563,316

Now, we try dividing 768,563,316 by 3:

768,563,316 ÷ 3 = 256,187,772

If the quotient is a whole number, then 3 and 256,187,772 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 3 256,187,772 384,281,658 768,563,316
-1 -2 -3 -256,187,772 -384,281,658 -768,563,316

Let's try dividing by 4:

768,563,316 ÷ 4 = 192,140,829

If the quotient is a whole number, then 4 and 192,140,829 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 4 192,140,829 256,187,772 384,281,658 768,563,316
-1 -2 -3 -4 -192,140,829 -256,187,772 -384,281,658 768,563,316
Keep dividing by the next highest number until you cannot divide anymore.

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