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 11,110,099, 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 | 11,110,099 | |
| -1 | -11,110,099 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 11,110,099.
Example:
1 x 11,110,099 = 11,110,099
and
-1 x -11,110,099 = 11,110,099
Notice both answers equal 11,110,099
With that explanation out of the way, let's continue. Next, we take the number 11,110,099 and divide it by 2:
11,110,099 ÷ 2 = 5,555,049.5
If the quotient is a whole number, then 2 and 5,555,049.5 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 | 11,110,099 | |
| -1 | -11,110,099 |
Now, we try dividing 11,110,099 by 3:
11,110,099 ÷ 3 = 3,703,366.3333
If the quotient is a whole number, then 3 and 3,703,366.3333 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 | 11,110,099 | |
| -1 | -11,110,099 |
Let's try dividing by 4:
11,110,099 ÷ 4 = 2,777,524.75
If the quotient is a whole number, then 4 and 2,777,524.75 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 | 11,110,099 | |
| -1 | 11,110,099 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 13 | 77 | 91 | 121 | 143 | 847 | 1,001 | 1,009 | 1,573 | 7,063 | 11,011 | 11,099 | 13,117 | 77,693 | 91,819 | 122,089 | 144,287 | 854,623 | 1,010,009 | 1,587,157 | 11,110,099 |
| -1 | -7 | -11 | -13 | -77 | -91 | -121 | -143 | -847 | -1,001 | -1,009 | -1,573 | -7,063 | -11,011 | -11,099 | -13,117 | -77,693 | -91,819 | -122,089 | -144,287 | -854,623 | -1,010,009 | -1,587,157 | -11,110,099 |
