How do I find the factor combinations of the number 660,512,256?

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 660,512,256, 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.

1 660,512,256
-1 -660,512,256

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 660,512,256.

Example:
1 x 660,512,256 = 660,512,256
and
-1 x -660,512,256 = 660,512,256
Notice both answers equal 660,512,256

With that explanation out of the way, let's continue. Next, we take the number 660,512,256 and divide it by 2:

660,512,256 ÷ 2 = 330,256,128

If the quotient is a whole number, then 2 and 330,256,128 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 2 330,256,128 660,512,256
-1 -2 -330,256,128 -660,512,256

Now, we try dividing 660,512,256 by 3:

660,512,256 ÷ 3 = 220,170,752

If the quotient is a whole number, then 3 and 220,170,752 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 3 220,170,752 330,256,128 660,512,256
-1 -2 -3 -220,170,752 -330,256,128 -660,512,256

Let's try dividing by 4:

660,512,256 ÷ 4 = 165,128,064

If the quotient is a whole number, then 4 and 165,128,064 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:

1 2 3 4 165,128,064 220,170,752 330,256,128 660,512,256
-1 -2 -3 -4 -165,128,064 -220,170,752 -330,256,128 660,512,256
Keep dividing by the next highest number until you cannot divide anymore.

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