How do I find the factor combinations of the number 314,215?

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 314,215, 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.

1 314,215
-1 -314,215

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 314,215.

Example:
1 x 314,215 = 314,215
and
-1 x -314,215 = 314,215
Notice both answers equal 314,215

With that explanation out of the way, let's continue. Next, we take the number 314,215 and divide it by 2:

314,215 ÷ 2 = 157,107.5

If the quotient is a whole number, then 2 and 157,107.5 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:

1 314,215
-1 -314,215

Now, we try dividing 314,215 by 3:

314,215 ÷ 3 = 104,738.3333

If the quotient is a whole number, then 3 and 104,738.3333 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:

1 314,215
-1 -314,215

Let's try dividing by 4:

314,215 ÷ 4 = 78,553.75

If the quotient is a whole number, then 4 and 78,553.75 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:

1 314,215
-1 314,215
Keep dividing by the next highest number until you cannot divide anymore.

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

151129551451973199851,5952,1675,71310,83528,56562,843314,215
