How do I find the factor combinations of the number 283,361?

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 283,361, 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.

1 283,361
-1 -283,361

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 283,361.

Example:
1 x 283,361 = 283,361
and
-1 x -283,361 = 283,361
Notice both answers equal 283,361

With that explanation out of the way, let's continue. Next, we take the number 283,361 and divide it by 2:

283,361 ÷ 2 = 141,680.5

If the quotient is a whole number, then 2 and 141,680.5 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:

1 283,361
-1 -283,361

Now, we try dividing 283,361 by 3:

283,361 ÷ 3 = 94,453.6667

If the quotient is a whole number, then 3 and 94,453.6667 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:

1 283,361
-1 -283,361

Let's try dividing by 4:

283,361 ÷ 4 = 70,840.25

If the quotient is a whole number, then 4 and 70,840.25 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:

1 283,361
-1 283,361
Keep dividing by the next highest number until you cannot divide anymore.

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

113713079233,99121,797283,361
-1-13-71-307-923-3,991-21,797-283,361
