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 11,510,885, 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 | 11,510,885 | |
| -1 | -11,510,885 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 11,510,885.
Example:
1 x 11,510,885 = 11,510,885
and
-1 x -11,510,885 = 11,510,885
Notice both answers equal 11,510,885
With that explanation out of the way, let's continue. Next, we take the number 11,510,885 and divide it by 2:
11,510,885 ÷ 2 = 5,755,442.5
If the quotient is a whole number, then 2 and 5,755,442.5 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 | 11,510,885 | |
| -1 | -11,510,885 |
Now, we try dividing 11,510,885 by 3:
11,510,885 ÷ 3 = 3,836,961.6667
If the quotient is a whole number, then 3 and 3,836,961.6667 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 | 11,510,885 | |
| -1 | -11,510,885 |
Let's try dividing by 4:
11,510,885 ÷ 4 = 2,877,721.25
If the quotient is a whole number, then 4 and 2,877,721.25 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 | 11,510,885 | |
| -1 | 11,510,885 |
If you did it right, you will end up with this table:
| 1 | 5 | 37 | 43 | 185 | 215 | 1,447 | 1,591 | 7,235 | 7,955 | 53,539 | 62,221 | 267,695 | 311,105 | 2,302,177 | 11,510,885 |
| -1 | -5 | -37 | -43 | -185 | -215 | -1,447 | -1,591 | -7,235 | -7,955 | -53,539 | -62,221 | -267,695 | -311,105 | -2,302,177 | -11,510,885 |
