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 33,685, it is easier to work with a table - it's called factoring from the outside in.
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 | 33,685 | |
-1 | -33,685 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 33,685.
Example:
1 x 33,685 = 33,685
and
-1 x -33,685 = 33,685
Notice both answers equal 33,685
With that explanation out of the way, let's continue. Next, we take the number 33,685 and divide it by 2:
33,685 ÷ 2 = 16,842.5
If the quotient is a whole number, then 2 and 16,842.5 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 | 33,685 | |
-1 | -33,685 |
Now, we try dividing 33,685 by 3:
33,685 ÷ 3 = 11,228.3333
If the quotient is a whole number, then 3 and 11,228.3333 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 | 33,685 | |
-1 | -33,685 |
Let's try dividing by 4:
33,685 ÷ 4 = 8,421.25
If the quotient is a whole number, then 4 and 8,421.25 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 | 33,685 | |
-1 | 33,685 |
If you did it right, you will end up with this table:
1 | 5 | 6,737 | 33,685 |
-1 | -5 | -6,737 | -33,685 |
