How do I find the factor combinations of the number 394,356?

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 394,356, 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.

1 394,356
-1 -394,356

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 394,356.

Example:
1 x 394,356 = 394,356
and
-1 x -394,356 = 394,356
Notice both answers equal 394,356

With that explanation out of the way, let's continue. Next, we take the number 394,356 and divide it by 2:

394,356 ÷ 2 = 197,178

If the quotient is a whole number, then 2 and 197,178 are factors. In this case, the quotient is a whole number. Write them in the table inside the other two factors like the below example. Don't forget to write the negative numbers too!

Here is what our table should look like at this step:

1 2 197,178 394,356
-1 -2 -197,178 -394,356

Now, we try dividing 394,356 by 3:

394,356 ÷ 3 = 131,452

If the quotient is a whole number, then 3 and 131,452 are factors. In this case, the quotient is a whole number. Write them in the table inside the other two factors like the below example. Don't forget to write the negative numbers too!

Here is what our table should look like at this step:

1 2 3 131,452 197,178 394,356
-1 -2 -3 -131,452 -197,178 -394,356

Let's try dividing by 4:

394,356 ÷ 4 = 98,589

If the quotient is a whole number, then 4 and 98,589 are factors. In this case, the quotient is a whole number. Write them in the table inside the other two factors like the below example. Don't forget to write the negative numbers too!

Here is what our table should look like at this step:

1 2 3 4 98,589 131,452 197,178 394,356
-1 -2 -3 -4 -98,589 -131,452 -197,178 394,356
Keep dividing by the next highest number until you cannot divide anymore.

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