How do I find the factor combinations of the number 660,048?

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 660,048, 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.

1 660,048
-1 -660,048

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 660,048.

Example:
1 x 660,048 = 660,048
and
-1 x -660,048 = 660,048
Notice both answers equal 660,048

With that explanation out of the way, let's continue. Next, we take the number 660,048 and divide it by 2:

660,048 ÷ 2 = 330,024

If the quotient is a whole number, then 2 and 330,024 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 2 330,024 660,048
-1 -2 -330,024 -660,048

Now, we try dividing 660,048 by 3:

660,048 ÷ 3 = 220,016

If the quotient is a whole number, then 3 and 220,016 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 3 220,016 330,024 660,048
-1 -2 -3 -220,016 -330,024 -660,048

Let's try dividing by 4:

660,048 ÷ 4 = 165,012

If the quotient is a whole number, then 4 and 165,012 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 4 165,012 220,016 330,024 660,048
-1 -2 -3 -4 -165,012 -220,016 -330,024 660,048
Keep dividing by the next highest number until you cannot divide anymore.

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