How do I find the factor combinations of the number 558,844?

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 558,844, 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.

1 558,844
-1 -558,844

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 558,844.

Example:
1 x 558,844 = 558,844
and
-1 x -558,844 = 558,844
Notice both answers equal 558,844

With that explanation out of the way, let's continue. Next, we take the number 558,844 and divide it by 2:

558,844 ÷ 2 = 279,422

If the quotient is a whole number, then 2 and 279,422 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 2 279,422 558,844
-1 -2 -279,422 -558,844

Now, we try dividing 558,844 by 3:

558,844 ÷ 3 = 186,281.3333

If the quotient is a whole number, then 3 and 186,281.3333 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 2 279,422 558,844
-1 -2 -279,422 -558,844

Let's try dividing by 4:

558,844 ÷ 4 = 139,711

If the quotient is a whole number, then 4 and 139,711 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 4 139,711 279,422 558,844
-1 -2 -4 -139,711 -279,422 558,844
Keep dividing by the next highest number until you cannot divide anymore.

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