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 11,906,885, 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 | 11,906,885 | |
| -1 | -11,906,885 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 11,906,885.
Example:
1 x 11,906,885 = 11,906,885
and
-1 x -11,906,885 = 11,906,885
Notice both answers equal 11,906,885
With that explanation out of the way, let's continue. Next, we take the number 11,906,885 and divide it by 2:
11,906,885 ÷ 2 = 5,953,442.5
If the quotient is a whole number, then 2 and 5,953,442.5 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 | 11,906,885 | |
| -1 | -11,906,885 |
Now, we try dividing 11,906,885 by 3:
11,906,885 ÷ 3 = 3,968,961.6667
If the quotient is a whole number, then 3 and 3,968,961.6667 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 | 11,906,885 | |
| -1 | -11,906,885 |
Let's try dividing by 4:
11,906,885 ÷ 4 = 2,976,721.25
If the quotient is a whole number, then 4 and 2,976,721.25 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 | 11,906,885 | |
| -1 | 11,906,885 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 85 | 127 | 635 | 1,103 | 2,159 | 5,515 | 10,795 | 18,751 | 93,755 | 140,081 | 700,405 | 2,381,377 | 11,906,885 |
| -1 | -5 | -17 | -85 | -127 | -635 | -1,103 | -2,159 | -5,515 | -10,795 | -18,751 | -93,755 | -140,081 | -700,405 | -2,381,377 | -11,906,885 |
