How do I find the factor combinations of the number 108,199?

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 108,199, 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.

1 108,199
-1 -108,199

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 108,199.

Example:
1 x 108,199 = 108,199
and
-1 x -108,199 = 108,199
Notice both answers equal 108,199

With that explanation out of the way, let's continue. Next, we take the number 108,199 and divide it by 2:

108,199 ÷ 2 = 54,099.5

If the quotient is a whole number, then 2 and 54,099.5 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:

1 108,199
-1 -108,199

Now, we try dividing 108,199 by 3:

108,199 ÷ 3 = 36,066.3333

If the quotient is a whole number, then 3 and 36,066.3333 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:

1 108,199
-1 -108,199

Let's try dividing by 4:

108,199 ÷ 4 = 27,049.75

If the quotient is a whole number, then 4 and 27,049.75 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:

1 108,199
-1 108,199
Keep dividing by the next highest number until you cannot divide anymore.

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

17132941912032873775331,1892,6393,7318,32315,457108,199
