How do I find the factor combinations of the number 79,235?

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 79,235, 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 79,235
-1 -79,235

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 79,235.

Example:
1 x 79,235 = 79,235
and
-1 x -79,235 = 79,235
Notice both answers equal 79,235

With that explanation out of the way, let's continue. Next, we take the number 79,235 and divide it by 2:

79,235 ÷ 2 = 39,617.5

If the quotient is a whole number, then 2 and 39,617.5 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 79,235
-1 -79,235

Now, we try dividing 79,235 by 3:

79,235 ÷ 3 = 26,411.6667

If the quotient is a whole number, then 3 and 26,411.6667 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 79,235
-1 -79,235

Let's try dividing by 4:

79,235 ÷ 4 = 19,808.75

If the quotient is a whole number, then 4 and 19,808.75 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 79,235
-1 79,235
Keep dividing by the next highest number until you cannot divide anymore.

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

15132353651152652996891,2191,4953,4456,09515,84779,235
