How do I find the factor combinations of the number 853,722,216?

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 853,722,216, 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.

1 853,722,216
-1 -853,722,216

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 853,722,216.

Example:
1 x 853,722,216 = 853,722,216
and
-1 x -853,722,216 = 853,722,216
Notice both answers equal 853,722,216

With that explanation out of the way, let's continue. Next, we take the number 853,722,216 and divide it by 2:

853,722,216 ÷ 2 = 426,861,108

If the quotient is a whole number, then 2 and 426,861,108 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 2 426,861,108 853,722,216
-1 -2 -426,861,108 -853,722,216

Now, we try dividing 853,722,216 by 3:

853,722,216 ÷ 3 = 284,574,072

If the quotient is a whole number, then 3 and 284,574,072 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 3 284,574,072 426,861,108 853,722,216
-1 -2 -3 -284,574,072 -426,861,108 -853,722,216

Let's try dividing by 4:

853,722,216 ÷ 4 = 213,430,554

If the quotient is a whole number, then 4 and 213,430,554 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 4 213,430,554 284,574,072 426,861,108 853,722,216
-1 -2 -3 -4 -213,430,554 -284,574,072 -426,861,108 853,722,216
Keep dividing by the next highest number until you cannot divide anymore.

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