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 10,081,085, 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 | 10,081,085 | |
| -1 | -10,081,085 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 10,081,085.
Example:
1 x 10,081,085 = 10,081,085
and
-1 x -10,081,085 = 10,081,085
Notice both answers equal 10,081,085
With that explanation out of the way, let's continue. Next, we take the number 10,081,085 and divide it by 2:
10,081,085 ÷ 2 = 5,040,542.5
If the quotient is a whole number, then 2 and 5,040,542.5 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 | 10,081,085 | |
| -1 | -10,081,085 |
Now, we try dividing 10,081,085 by 3:
10,081,085 ÷ 3 = 3,360,361.6667
If the quotient is a whole number, then 3 and 3,360,361.6667 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 | 10,081,085 | |
| -1 | -10,081,085 |
Let's try dividing by 4:
10,081,085 ÷ 4 = 2,520,271.25
If the quotient is a whole number, then 4 and 2,520,271.25 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 | 10,081,085 | |
| -1 | 10,081,085 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 17 | 35 | 85 | 119 | 595 | 16,943 | 84,715 | 118,601 | 288,031 | 593,005 | 1,440,155 | 2,016,217 | 10,081,085 |
| -1 | -5 | -7 | -17 | -35 | -85 | -119 | -595 | -16,943 | -84,715 | -118,601 | -288,031 | -593,005 | -1,440,155 | -2,016,217 | -10,081,085 |
