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 11,109,995, 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 | 11,109,995 | |
| -1 | -11,109,995 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 11,109,995.
Example:
1 x 11,109,995 = 11,109,995
and
-1 x -11,109,995 = 11,109,995
Notice both answers equal 11,109,995
With that explanation out of the way, let's continue. Next, we take the number 11,109,995 and divide it by 2:
11,109,995 ÷ 2 = 5,554,997.5
If the quotient is a whole number, then 2 and 5,554,997.5 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 | 11,109,995 | |
| -1 | -11,109,995 |
Now, we try dividing 11,109,995 by 3:
11,109,995 ÷ 3 = 3,703,331.6667
If the quotient is a whole number, then 3 and 3,703,331.6667 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 | 11,109,995 | |
| -1 | -11,109,995 |
Let's try dividing by 4:
11,109,995 ÷ 4 = 2,777,498.75
If the quotient is a whole number, then 4 and 2,777,498.75 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 | 11,109,995 | |
| -1 | 11,109,995 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 59 | 65 | 295 | 767 | 2,897 | 3,835 | 14,485 | 37,661 | 170,923 | 188,305 | 854,615 | 2,221,999 | 11,109,995 |
| -1 | -5 | -13 | -59 | -65 | -295 | -767 | -2,897 | -3,835 | -14,485 | -37,661 | -170,923 | -188,305 | -854,615 | -2,221,999 | -11,109,995 |
