How do I find the factor combinations of the number 853,715?

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 853,715, 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.

1 853,715
-1 -853,715

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 853,715.

Example:
1 x 853,715 = 853,715
and
-1 x -853,715 = 853,715
Notice both answers equal 853,715

With that explanation out of the way, let's continue. Next, we take the number 853,715 and divide it by 2:

853,715 ÷ 2 = 426,857.5

If the quotient is a whole number, then 2 and 426,857.5 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.

Here is what our table should look like at this step:

1 853,715
-1 -853,715

Now, we try dividing 853,715 by 3:

853,715 ÷ 3 = 284,571.6667

If the quotient is a whole number, then 3 and 284,571.6667 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.

Here is what our table should look like at this step:

1 853,715
-1 -853,715

Let's try dividing by 4:

853,715 ÷ 4 = 213,428.75

If the quotient is a whole number, then 4 and 213,428.75 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.

Here is what our table should look like at this step:

1 853,715
-1 853,715
Keep dividing by the next highest number until you cannot divide anymore.

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

151135651,5117,555170,743853,715
-1-5-113-565-1,511-7,555-170,743-853,715
