How do I find the factor combinations of the number 319,835?

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 319,835, 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.

1 319,835
-1 -319,835

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 319,835.

Example:
1 x 319,835 = 319,835
and
-1 x -319,835 = 319,835
Notice both answers equal 319,835

With that explanation out of the way, let's continue. Next, we take the number 319,835 and divide it by 2:

319,835 ÷ 2 = 159,917.5

If the quotient is a whole number, then 2 and 159,917.5 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:

1 319,835
-1 -319,835

Now, we try dividing 319,835 by 3:

319,835 ÷ 3 = 106,611.6667

If the quotient is a whole number, then 3 and 106,611.6667 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:

1 319,835
-1 -319,835

Let's try dividing by 4:

319,835 ÷ 4 = 79,958.75

If the quotient is a whole number, then 4 and 79,958.75 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:

1 319,835
-1 319,835
Keep dividing by the next highest number until you cannot divide anymore.

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

15472351,3616,80563,967319,835
-1-5-47-235-1,361-6,805-63,967-319,835
