How do I find the factor combinations of the number 823,178,856?

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 823,178,856, 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.

1 823,178,856
-1 -823,178,856

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 823,178,856.

Example:
1 x 823,178,856 = 823,178,856
and
-1 x -823,178,856 = 823,178,856
Notice both answers equal 823,178,856

With that explanation out of the way, let's continue. Next, we take the number 823,178,856 and divide it by 2:

823,178,856 ÷ 2 = 411,589,428

If the quotient is a whole number, then 2 and 411,589,428 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 2 411,589,428 823,178,856
-1 -2 -411,589,428 -823,178,856

Now, we try dividing 823,178,856 by 3:

823,178,856 ÷ 3 = 274,392,952

If the quotient is a whole number, then 3 and 274,392,952 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 3 274,392,952 411,589,428 823,178,856
-1 -2 -3 -274,392,952 -411,589,428 -823,178,856

Let's try dividing by 4:

823,178,856 ÷ 4 = 205,794,714

If the quotient is a whole number, then 4 and 205,794,714 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 4 205,794,714 274,392,952 411,589,428 823,178,856
-1 -2 -3 -4 -205,794,714 -274,392,952 -411,589,428 823,178,856
Keep dividing by the next highest number until you cannot divide anymore.

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