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 11,188,135, 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 | 11,188,135 | |
| -1 | -11,188,135 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 11,188,135.
Example:
1 x 11,188,135 = 11,188,135
and
-1 x -11,188,135 = 11,188,135
Notice both answers equal 11,188,135
With that explanation out of the way, let's continue. Next, we take the number 11,188,135 and divide it by 2:
11,188,135 ÷ 2 = 5,594,067.5
If the quotient is a whole number, then 2 and 5,594,067.5 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 | 11,188,135 | |
| -1 | -11,188,135 |
Now, we try dividing 11,188,135 by 3:
11,188,135 ÷ 3 = 3,729,378.3333
If the quotient is a whole number, then 3 and 3,729,378.3333 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 | 11,188,135 | |
| -1 | -11,188,135 |
Let's try dividing by 4:
11,188,135 ÷ 4 = 2,797,033.75
If the quotient is a whole number, then 4 and 2,797,033.75 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 | 11,188,135 | |
| -1 | 11,188,135 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 373 | 857 | 1,865 | 2,611 | 4,285 | 5,999 | 13,055 | 29,995 | 319,661 | 1,598,305 | 2,237,627 | 11,188,135 |
| -1 | -5 | -7 | -35 | -373 | -857 | -1,865 | -2,611 | -4,285 | -5,999 | -13,055 | -29,995 | -319,661 | -1,598,305 | -2,237,627 | -11,188,135 |
