How do I find the factor combinations of the number 494,039?

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 494,039, 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.

1 494,039
-1 -494,039

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 494,039.

Example:
1 x 494,039 = 494,039
and
-1 x -494,039 = 494,039
Notice both answers equal 494,039

With that explanation out of the way, let's continue. Next, we take the number 494,039 and divide it by 2:

494,039 ÷ 2 = 247,019.5

If the quotient is a whole number, then 2 and 247,019.5 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:

1 494,039
-1 -494,039

Now, we try dividing 494,039 by 3:

494,039 ÷ 3 = 164,679.6667

If the quotient is a whole number, then 3 and 164,679.6667 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:

1 494,039
-1 -494,039

Let's try dividing by 4:

494,039 ÷ 4 = 123,509.75

If the quotient is a whole number, then 4 and 123,509.75 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:

1 494,039
-1 494,039
Keep dividing by the next highest number until you cannot divide anymore.

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

17136189914276237931,1575,4295,5518,09938,00370,577494,039
-1-7-13-61-89-91-427-623-793-1,157-5,429-5,551-8,099-38,003-70,577-494,039
