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

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 587,587, 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.

1 587,587
-1 -587,587

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 587,587.

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

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

587,587 ÷ 2 = 293,793.5

If the quotient is a whole number, then 2 and 293,793.5 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:

1 587,587
-1 -587,587

Now, we try dividing 587,587 by 3:

587,587 ÷ 3 = 195,862.3333

If the quotient is a whole number, then 3 and 195,862.3333 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:

1 587,587
-1 -587,587

Let's try dividing by 4:

587,587 ÷ 4 = 146,896.75

If the quotient is a whole number, then 4 and 146,896.75 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:

1 587,587
-1 587,587
Keep dividing by the next highest number until you cannot divide anymore.

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

17111377911435871,0014,1096,4577,63145,19953,41783,941587,587
