How do I find the factor combinations of the number 215,033?

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 215,033, 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.

1 215,033
-1 -215,033

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 215,033.

Example:
1 x 215,033 = 215,033
and
-1 x -215,033 = 215,033
Notice both answers equal 215,033

With that explanation out of the way, let's continue. Next, we take the number 215,033 and divide it by 2:

215,033 ÷ 2 = 107,516.5

If the quotient is a whole number, then 2 and 107,516.5 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:

1 215,033
-1 -215,033

Now, we try dividing 215,033 by 3:

215,033 ÷ 3 = 71,677.6667

If the quotient is a whole number, then 3 and 71,677.6667 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:

1 215,033
-1 -215,033

Let's try dividing by 4:

215,033 ÷ 4 = 53,758.25

If the quotient is a whole number, then 4 and 53,758.25 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:

1 215,033
-1 215,033
Keep dividing by the next highest number until you cannot divide anymore.

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

171317911191392219731,5471,8072,36312,64916,54130,719215,033
