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 8,086,585, 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 | 8,086,585 | |
| -1 | -8,086,585 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,086,585.
Example:
1 x 8,086,585 = 8,086,585
and
-1 x -8,086,585 = 8,086,585
Notice both answers equal 8,086,585
With that explanation out of the way, let's continue. Next, we take the number 8,086,585 and divide it by 2:
8,086,585 ÷ 2 = 4,043,292.5
If the quotient is a whole number, then 2 and 4,043,292.5 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 | 8,086,585 | |
| -1 | -8,086,585 |
Now, we try dividing 8,086,585 by 3:
8,086,585 ÷ 3 = 2,695,528.3333
If the quotient is a whole number, then 3 and 2,695,528.3333 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 | 8,086,585 | |
| -1 | -8,086,585 |
Let's try dividing by 4:
8,086,585 ÷ 4 = 2,021,646.25
If the quotient is a whole number, then 4 and 2,021,646.25 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 | 8,086,585 | |
| -1 | 8,086,585 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 47 | 65 | 235 | 611 | 2,647 | 3,055 | 13,235 | 34,411 | 124,409 | 172,055 | 622,045 | 1,617,317 | 8,086,585 |
| -1 | -5 | -13 | -47 | -65 | -235 | -611 | -2,647 | -3,055 | -13,235 | -34,411 | -124,409 | -172,055 | -622,045 | -1,617,317 | -8,086,585 |
