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 7,665,317, 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 | 7,665,317 | |
| -1 | -7,665,317 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,665,317.
Example:
1 x 7,665,317 = 7,665,317
and
-1 x -7,665,317 = 7,665,317
Notice both answers equal 7,665,317
With that explanation out of the way, let's continue. Next, we take the number 7,665,317 and divide it by 2:
7,665,317 ÷ 2 = 3,832,658.5
If the quotient is a whole number, then 2 and 3,832,658.5 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 | 7,665,317 | |
| -1 | -7,665,317 |
Now, we try dividing 7,665,317 by 3:
7,665,317 ÷ 3 = 2,555,105.6667
If the quotient is a whole number, then 3 and 2,555,105.6667 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 | 7,665,317 | |
| -1 | -7,665,317 |
Let's try dividing by 4:
7,665,317 ÷ 4 = 1,916,329.25
If the quotient is a whole number, then 4 and 1,916,329.25 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 | 7,665,317 | |
| -1 | 7,665,317 |
If you did it right, you will end up with this table:
| 1 | 11 | 17 | 179 | 187 | 229 | 1,969 | 2,519 | 3,043 | 3,893 | 33,473 | 40,991 | 42,823 | 450,901 | 696,847 | 7,665,317 |
| -1 | -11 | -17 | -179 | -187 | -229 | -1,969 | -2,519 | -3,043 | -3,893 | -33,473 | -40,991 | -42,823 | -450,901 | -696,847 | -7,665,317 |
