How do I find the factor combinations of the number 284,585?

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 284,585, 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.

1 284,585
-1 -284,585

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 284,585.

Example:
1 x 284,585 = 284,585
and
-1 x -284,585 = 284,585
Notice both answers equal 284,585

With that explanation out of the way, let's continue. Next, we take the number 284,585 and divide it by 2:

284,585 ÷ 2 = 142,292.5

If the quotient is a whole number, then 2 and 142,292.5 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:

1 284,585
-1 -284,585

Now, we try dividing 284,585 by 3:

284,585 ÷ 3 = 94,861.6667

If the quotient is a whole number, then 3 and 94,861.6667 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:

1 284,585
-1 -284,585

Let's try dividing by 4:

284,585 ÷ 4 = 71,146.25

If the quotient is a whole number, then 4 and 71,146.25 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:

1 284,585
-1 284,585
Keep dividing by the next highest number until you cannot divide anymore.

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

15735471732353298651,2111,6456,0558,13140,65556,917284,585
