How do I find the factor combinations of the number 303,504?

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 303,504, 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.

1 303,504
-1 -303,504

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 303,504.

Example:
1 x 303,504 = 303,504
and
-1 x -303,504 = 303,504
Notice both answers equal 303,504

With that explanation out of the way, let's continue. Next, we take the number 303,504 and divide it by 2:

303,504 ÷ 2 = 151,752

If the quotient is a whole number, then 2 and 151,752 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 2 151,752 303,504
-1 -2 -151,752 -303,504

Now, we try dividing 303,504 by 3:

303,504 ÷ 3 = 101,168

If the quotient is a whole number, then 3 and 101,168 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 3 101,168 151,752 303,504
-1 -2 -3 -101,168 -151,752 -303,504

Let's try dividing by 4:

303,504 ÷ 4 = 75,876

If the quotient is a whole number, then 4 and 75,876 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 75,876 101,168 151,752 303,504
-1 -2 -3 -4 -75,876 -101,168 -151,752 303,504
Keep dividing by the next highest number until you cannot divide anymore.

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