How do I find the factor combinations of the number 48,875?

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 48,875, 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 48,875
-1 -48,875

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 48,875.

Example:
1 x 48,875 = 48,875
and
-1 x -48,875 = 48,875
Notice both answers equal 48,875

With that explanation out of the way, let's continue. Next, we take the number 48,875 and divide it by 2:

48,875 ÷ 2 = 24,437.5

If the quotient is a whole number, then 2 and 24,437.5 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 48,875
-1 -48,875

Now, we try dividing 48,875 by 3:

48,875 ÷ 3 = 16,291.6667

If the quotient is a whole number, then 3 and 16,291.6667 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 48,875
-1 -48,875

Let's try dividing by 4:

48,875 ÷ 4 = 12,218.75

If the quotient is a whole number, then 4 and 12,218.75 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 48,875
-1 48,875
Keep dividing by the next highest number until you cannot divide anymore.

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

15172325851151253914255751,9552,1252,8759,77548,875
