How do I find the factor combinations of the number 285,383?

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 285,383, 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.

1 285,383
-1 -285,383

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 285,383.

Example:
1 x 285,383 = 285,383
and
-1 x -285,383 = 285,383
Notice both answers equal 285,383

With that explanation out of the way, let's continue. Next, we take the number 285,383 and divide it by 2:

285,383 ÷ 2 = 142,691.5

If the quotient is a whole number, then 2 and 142,691.5 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:

1 285,383
-1 -285,383

Now, we try dividing 285,383 by 3:

285,383 ÷ 3 = 95,127.6667

If the quotient is a whole number, then 3 and 95,127.6667 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:

1 285,383
-1 -285,383

Let's try dividing by 4:

285,383 ÷ 4 = 71,345.75

If the quotient is a whole number, then 4 and 71,345.75 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:

1 285,383
-1 285,383
Keep dividing by the next highest number until you cannot divide anymore.

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

17594136914,83740,769285,383
-1-7-59-413-691-4,837-40,769-285,383
