How do I find the factor combinations of the number 282,475?

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 282,475, 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.

1 282,475
-1 -282,475

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 282,475.

Example:
1 x 282,475 = 282,475
and
-1 x -282,475 = 282,475
Notice both answers equal 282,475

With that explanation out of the way, let's continue. Next, we take the number 282,475 and divide it by 2:

282,475 ÷ 2 = 141,237.5

If the quotient is a whole number, then 2 and 141,237.5 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:

1 282,475
-1 -282,475

Now, we try dividing 282,475 by 3:

282,475 ÷ 3 = 94,158.3333

If the quotient is a whole number, then 3 and 94,158.3333 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:

1 282,475
-1 -282,475

Let's try dividing by 4:

282,475 ÷ 4 = 70,618.75

If the quotient is a whole number, then 4 and 70,618.75 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:

1 282,475
-1 282,475
Keep dividing by the next highest number until you cannot divide anymore.

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

152511,29956,495282,475
-1-5-25-11,299-56,495-282,475
