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 8,635,081, 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 | 8,635,081 | |
| -1 | -8,635,081 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,635,081.
Example:
1 x 8,635,081 = 8,635,081
and
-1 x -8,635,081 = 8,635,081
Notice both answers equal 8,635,081
With that explanation out of the way, let's continue. Next, we take the number 8,635,081 and divide it by 2:
8,635,081 ÷ 2 = 4,317,540.5
If the quotient is a whole number, then 2 and 4,317,540.5 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 | 8,635,081 | |
| -1 | -8,635,081 |
Now, we try dividing 8,635,081 by 3:
8,635,081 ÷ 3 = 2,878,360.3333
If the quotient is a whole number, then 3 and 2,878,360.3333 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 | 8,635,081 | |
| -1 | -8,635,081 |
Let's try dividing by 4:
8,635,081 ÷ 4 = 2,158,770.25
If the quotient is a whole number, then 4 and 2,158,770.25 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 | 8,635,081 | |
| -1 | 8,635,081 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 31 | 91 | 217 | 403 | 2,821 | 3,061 | 21,427 | 39,793 | 94,891 | 278,551 | 664,237 | 1,233,583 | 8,635,081 |
| -1 | -7 | -13 | -31 | -91 | -217 | -403 | -2,821 | -3,061 | -21,427 | -39,793 | -94,891 | -278,551 | -664,237 | -1,233,583 | -8,635,081 |
