How do I find the factor combinations of the number 904,715?

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 904,715, 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.

1 904,715
-1 -904,715

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 904,715.

Example:
1 x 904,715 = 904,715
and
-1 x -904,715 = 904,715
Notice both answers equal 904,715

With that explanation out of the way, let's continue. Next, we take the number 904,715 and divide it by 2:

904,715 ÷ 2 = 452,357.5

If the quotient is a whole number, then 2 and 452,357.5 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:

1 904,715
-1 -904,715

Now, we try dividing 904,715 by 3:

904,715 ÷ 3 = 301,571.6667

If the quotient is a whole number, then 3 and 301,571.6667 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:

1 904,715
-1 -904,715

Let's try dividing by 4:

904,715 ÷ 4 = 226,178.75

If the quotient is a whole number, then 4 and 226,178.75 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:

1 904,715
-1 904,715
Keep dividing by the next highest number until you cannot divide anymore.

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

1573525,849129,245180,943904,715
-1-5-7-35-25,849-129,245-180,943-904,715
