How do I find the factor combinations of the number 509,100?

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 509,100, 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.

1 509,100
-1 -509,100

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 509,100.

Example:
1 x 509,100 = 509,100
and
-1 x -509,100 = 509,100
Notice both answers equal 509,100

With that explanation out of the way, let's continue. Next, we take the number 509,100 and divide it by 2:

509,100 ÷ 2 = 254,550

If the quotient is a whole number, then 2 and 254,550 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 2 254,550 509,100
-1 -2 -254,550 -509,100

Now, we try dividing 509,100 by 3:

509,100 ÷ 3 = 169,700

If the quotient is a whole number, then 3 and 169,700 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 3 169,700 254,550 509,100
-1 -2 -3 -169,700 -254,550 -509,100

Let's try dividing by 4:

509,100 ÷ 4 = 127,275

If the quotient is a whole number, then 4 and 127,275 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 4 127,275 169,700 254,550 509,100
-1 -2 -3 -4 -127,275 -169,700 -254,550 509,100
Keep dividing by the next highest number until you cannot divide anymore.

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