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 79,715, 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 | 79,715 | |
-1 | -79,715 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 79,715.
Example:
1 x 79,715 = 79,715
and
-1 x -79,715 = 79,715
Notice both answers equal 79,715
With that explanation out of the way, let's continue. Next, we take the number 79,715 and divide it by 2:
79,715 ÷ 2 = 39,857.5
If the quotient is a whole number, then 2 and 39,857.5 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 | 79,715 | |
-1 | -79,715 |
Now, we try dividing 79,715 by 3:
79,715 ÷ 3 = 26,571.6667
If the quotient is a whole number, then 3 and 26,571.6667 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 | 79,715 | |
-1 | -79,715 |
Let's try dividing by 4:
79,715 ÷ 4 = 19,928.75
If the quotient is a whole number, then 4 and 19,928.75 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 | 79,715 | |
-1 | 79,715 |
If you did it right, you will end up with this table:
1 | 5 | 107 | 149 | 535 | 745 | 15,943 | 79,715 |
-1 | -5 | -107 | -149 | -535 | -745 | -15,943 | -79,715 |
