How do I find the factor combinations of the number 97,559?

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 97,559, 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 97,559
-1 -97,559

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 97,559.

Example:
1 x 97,559 = 97,559
and
-1 x -97,559 = 97,559
Notice both answers equal 97,559

With that explanation out of the way, let's continue. Next, we take the number 97,559 and divide it by 2:

97,559 ÷ 2 = 48,779.5

If the quotient is a whole number, then 2 and 48,779.5 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 97,559
-1 -97,559

Now, we try dividing 97,559 by 3:

97,559 ÷ 3 = 32,519.6667

If the quotient is a whole number, then 3 and 32,519.6667 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 97,559
-1 -97,559

Let's try dividing by 4:

97,559 ÷ 4 = 24,389.75

If the quotient is a whole number, then 4 and 24,389.75 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 97,559
-1 97,559
Keep dividing by the next highest number until you cannot divide anymore.

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

171149771815391,2671,9918,86913,93797,559
