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 8,408,317, 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 | 8,408,317 | |
| -1 | -8,408,317 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,408,317.
Example:
1 x 8,408,317 = 8,408,317
and
-1 x -8,408,317 = 8,408,317
Notice both answers equal 8,408,317
With that explanation out of the way, let's continue. Next, we take the number 8,408,317 and divide it by 2:
8,408,317 ÷ 2 = 4,204,158.5
If the quotient is a whole number, then 2 and 4,204,158.5 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 | 8,408,317 | |
| -1 | -8,408,317 |
Now, we try dividing 8,408,317 by 3:
8,408,317 ÷ 3 = 2,802,772.3333
If the quotient is a whole number, then 3 and 2,802,772.3333 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 | 8,408,317 | |
| -1 | -8,408,317 |
Let's try dividing by 4:
8,408,317 ÷ 4 = 2,102,079.25
If the quotient is a whole number, then 4 and 2,102,079.25 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 | 8,408,317 | |
| -1 | 8,408,317 |
If you did it right, you will end up with this table:
| 1 | 19 | 23 | 71 | 271 | 437 | 1,349 | 1,633 | 5,149 | 6,233 | 19,241 | 31,027 | 118,427 | 365,579 | 442,543 | 8,408,317 |
| -1 | -19 | -23 | -71 | -271 | -437 | -1,349 | -1,633 | -5,149 | -6,233 | -19,241 | -31,027 | -118,427 | -365,579 | -442,543 | -8,408,317 |
