Q: What are the factor combinations of the number 935?

 A:
Positive:   1 x 9355 x 18711 x 8517 x 55
Negative: -1 x -935-5 x -187-11 x -85-17 x -55


How do I find the factor combinations of the number 935?

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 935, 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.

1 935
-1 -935

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 935.

Example:
1 x 935 = 935
and
-1 x -935 = 935
Notice both answers equal 935

With that explanation out of the way, let's continue. Next, we take the number 935 and divide it by 2:

935 ÷ 2 = 467.5

If the quotient is a whole number, then 2 and 467.5 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:

1 935
-1 -935

Now, we try dividing 935 by 3:

935 ÷ 3 = 311.6667

If the quotient is a whole number, then 3 and 311.6667 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:

1 935
-1 -935

Let's try dividing by 4:

935 ÷ 4 = 233.75

If the quotient is a whole number, then 4 and 233.75 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:

1 935
-1 935
Keep dividing by the next highest number until you cannot divide anymore.

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

1511175585187935
-1-5-11-17-55-85-187-935
