How do I find the factor combinations of the number 904,655?

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 904,655, 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.

1 904,655
-1 -904,655

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 904,655.

Example:
1 x 904,655 = 904,655
and
-1 x -904,655 = 904,655
Notice both answers equal 904,655

With that explanation out of the way, let's continue. Next, we take the number 904,655 and divide it by 2:

904,655 ÷ 2 = 452,327.5

If the quotient is a whole number, then 2 and 452,327.5 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:

1 904,655
-1 -904,655

Now, we try dividing 904,655 by 3:

904,655 ÷ 3 = 301,551.6667

If the quotient is a whole number, then 3 and 301,551.6667 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:

1 904,655
-1 -904,655

Let's try dividing by 4:

904,655 ÷ 4 = 226,163.75

If the quotient is a whole number, then 4 and 226,163.75 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:

1 904,655
-1 904,655
Keep dividing by the next highest number until you cannot divide anymore.

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

151729851453674931,8352,4656,23910,64331,19553,215180,931904,655
