How do I find the factor combinations of the number 320,795?

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 320,795, 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.

1 320,795
-1 -320,795

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 320,795.

Example:
1 x 320,795 = 320,795
and
-1 x -320,795 = 320,795
Notice both answers equal 320,795

With that explanation out of the way, let's continue. Next, we take the number 320,795 and divide it by 2:

320,795 ÷ 2 = 160,397.5

If the quotient is a whole number, then 2 and 160,397.5 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:

1 320,795
-1 -320,795

Now, we try dividing 320,795 by 3:

320,795 ÷ 3 = 106,931.6667

If the quotient is a whole number, then 3 and 106,931.6667 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:

1 320,795
-1 -320,795

Let's try dividing by 4:

320,795 ÷ 4 = 80,198.75

If the quotient is a whole number, then 4 and 80,198.75 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:

1 320,795
-1 320,795
Keep dividing by the next highest number until you cannot divide anymore.

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

15834157733,86564,159320,795
-1-5-83-415-773-3,865-64,159-320,795
