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 8,088,665, 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 | 8,088,665 | |
| -1 | -8,088,665 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,088,665.
Example:
1 x 8,088,665 = 8,088,665
and
-1 x -8,088,665 = 8,088,665
Notice both answers equal 8,088,665
With that explanation out of the way, let's continue. Next, we take the number 8,088,665 and divide it by 2:
8,088,665 ÷ 2 = 4,044,332.5
If the quotient is a whole number, then 2 and 4,044,332.5 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 | 8,088,665 | |
| -1 | -8,088,665 |
Now, we try dividing 8,088,665 by 3:
8,088,665 ÷ 3 = 2,696,221.6667
If the quotient is a whole number, then 3 and 2,696,221.6667 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 | 8,088,665 | |
| -1 | -8,088,665 |
Let's try dividing by 4:
8,088,665 ÷ 4 = 2,022,166.25
If the quotient is a whole number, then 4 and 2,022,166.25 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 | 8,088,665 | |
| -1 | 8,088,665 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 107 | 535 | 1,163 | 1,391 | 5,815 | 6,955 | 15,119 | 75,595 | 124,441 | 622,205 | 1,617,733 | 8,088,665 |
| -1 | -5 | -13 | -65 | -107 | -535 | -1,163 | -1,391 | -5,815 | -6,955 | -15,119 | -75,595 | -124,441 | -622,205 | -1,617,733 | -8,088,665 |
