How do I find the factor combinations of the number 329,225?

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 329,225, 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.

1 329,225
-1 -329,225

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 329,225.

Example:
1 x 329,225 = 329,225
and
-1 x -329,225 = 329,225
Notice both answers equal 329,225

With that explanation out of the way, let's continue. Next, we take the number 329,225 and divide it by 2:

329,225 ÷ 2 = 164,612.5

If the quotient is a whole number, then 2 and 164,612.5 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:

1 329,225
-1 -329,225

Now, we try dividing 329,225 by 3:

329,225 ÷ 3 = 109,741.6667

If the quotient is a whole number, then 3 and 109,741.6667 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:

1 329,225
-1 -329,225

Let's try dividing by 4:

329,225 ÷ 4 = 82,306.25

If the quotient is a whole number, then 4 and 82,306.25 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:

1 329,225
-1 329,225
Keep dividing by the next highest number until you cannot divide anymore.

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

151325653251,0135,06513,16925,32565,845329,225
-1-5-13-25-65-325-1,013-5,065-13,169-25,325-65,845-329,225
