How do I find the factor combinations of the number 209,208?

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 209,208, 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.

1 209,208
-1 -209,208

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 209,208.

Example:
1 x 209,208 = 209,208
and
-1 x -209,208 = 209,208
Notice both answers equal 209,208

With that explanation out of the way, let's continue. Next, we take the number 209,208 and divide it by 2:

209,208 ÷ 2 = 104,604

If the quotient is a whole number, then 2 and 104,604 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 2 104,604 209,208
-1 -2 -104,604 -209,208

Now, we try dividing 209,208 by 3:

209,208 ÷ 3 = 69,736

If the quotient is a whole number, then 3 and 69,736 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 69,736 104,604 209,208
-1 -2 -3 -69,736 -104,604 -209,208

Let's try dividing by 4:

209,208 ÷ 4 = 52,302

If the quotient is a whole number, then 4 and 52,302 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 52,302 69,736 104,604 209,208
-1 -2 -3 -4 -52,302 -69,736 -104,604 209,208
Keep dividing by the next highest number until you cannot divide anymore.

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