How do I find the factor combinations of the number 54,587?

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 54,587, 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 54,587
-1 -54,587

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 54,587.

Example:
1 x 54,587 = 54,587
and
-1 x -54,587 = 54,587
Notice both answers equal 54,587

With that explanation out of the way, let's continue. Next, we take the number 54,587 and divide it by 2:

54,587 ÷ 2 = 27,293.5

If the quotient is a whole number, then 2 and 27,293.5 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 54,587
-1 -54,587

Now, we try dividing 54,587 by 3:

54,587 ÷ 3 = 18,195.6667

If the quotient is a whole number, then 3 and 18,195.6667 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 54,587
-1 -54,587

Let's try dividing by 4:

54,587 ÷ 4 = 13,646.75

If the quotient is a whole number, then 4 and 13,646.75 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 54,587
-1 54,587
Keep dividing by the next highest number until you cannot divide anymore.

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

11317191692212473232,8733,2114,19954,587
