How do I find the factor combinations of the number 342,727?

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 342,727, 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.

1 342,727
-1 -342,727

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 342,727.

Example:
1 x 342,727 = 342,727
and
-1 x -342,727 = 342,727
Notice both answers equal 342,727

With that explanation out of the way, let's continue. Next, we take the number 342,727 and divide it by 2:

342,727 ÷ 2 = 171,363.5

If the quotient is a whole number, then 2 and 171,363.5 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:

1 342,727
-1 -342,727

Now, we try dividing 342,727 by 3:

342,727 ÷ 3 = 114,242.3333

If the quotient is a whole number, then 3 and 114,242.3333 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:

1 342,727
-1 -342,727

Let's try dividing by 4:

342,727 ÷ 4 = 85,681.75

If the quotient is a whole number, then 4 and 85,681.75 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:

1 342,727
-1 342,727
Keep dividing by the next highest number until you cannot divide anymore.

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

1711774,45131,15748,961342,727
-1-7-11-77-4,451-31,157-48,961-342,727
