How do I find the factor combinations of the number 47,585?

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 47,585, 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 47,585
-1 -47,585

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 47,585.

Example:
1 x 47,585 = 47,585
and
-1 x -47,585 = 47,585
Notice both answers equal 47,585

With that explanation out of the way, let's continue. Next, we take the number 47,585 and divide it by 2:

47,585 ÷ 2 = 23,792.5

If the quotient is a whole number, then 2 and 23,792.5 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 47,585
-1 -47,585

Now, we try dividing 47,585 by 3:

47,585 ÷ 3 = 15,861.6667

If the quotient is a whole number, then 3 and 15,861.6667 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 47,585
-1 -47,585

Let's try dividing by 4:

47,585 ÷ 4 = 11,896.25

If the quotient is a whole number, then 4 and 11,896.25 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 47,585
-1 47,585
Keep dividing by the next highest number until you cannot divide anymore.

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

15311553071,5359,51747,585
-1-5-31-155-307-1,535-9,517-47,585
