Q: What are the factor combinations of the number 595?

 A:
Positive:   1 x 5955 x 1197 x 8517 x 35
Negative: -1 x -595-5 x -119-7 x -85-17 x -35


How do I find the factor combinations of the number 595?

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 595, 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.

1 595
-1 -595

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 595.

Example:
1 x 595 = 595
and
-1 x -595 = 595
Notice both answers equal 595

With that explanation out of the way, let's continue. Next, we take the number 595 and divide it by 2:

595 ÷ 2 = 297.5

If the quotient is a whole number, then 2 and 297.5 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:

1 595
-1 -595

Now, we try dividing 595 by 3:

595 ÷ 3 = 198.3333

If the quotient is a whole number, then 3 and 198.3333 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:

1 595
-1 -595

Let's try dividing by 4:

595 ÷ 4 = 148.75

If the quotient is a whole number, then 4 and 148.75 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:

1 595
-1 595
Keep dividing by the next highest number until you cannot divide anymore.

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

157173585119595
-1-5-7-17-35-85-119-595
