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 11,111,089, 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 | 11,111,089 | |
| -1 | -11,111,089 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 11,111,089.
Example:
1 x 11,111,089 = 11,111,089
and
-1 x -11,111,089 = 11,111,089
Notice both answers equal 11,111,089
With that explanation out of the way, let's continue. Next, we take the number 11,111,089 and divide it by 2:
11,111,089 ÷ 2 = 5,555,544.5
If the quotient is a whole number, then 2 and 5,555,544.5 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 | 11,111,089 | |
| -1 | -11,111,089 |
Now, we try dividing 11,111,089 by 3:
11,111,089 ÷ 3 = 3,703,696.3333
If the quotient is a whole number, then 3 and 3,703,696.3333 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 | 11,111,089 | |
| -1 | -11,111,089 |
Let's try dividing by 4:
11,111,089 ÷ 4 = 2,777,772.25
If the quotient is a whole number, then 4 and 2,777,772.25 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 | 11,111,089 | |
| -1 | 11,111,089 |
If you did it right, you will end up with this table:
| 1 | 11 | 29 | 61 | 319 | 571 | 671 | 1,769 | 6,281 | 16,559 | 19,459 | 34,831 | 182,149 | 383,141 | 1,010,099 | 11,111,089 |
| -1 | -11 | -29 | -61 | -319 | -571 | -671 | -1,769 | -6,281 | -16,559 | -19,459 | -34,831 | -182,149 | -383,141 | -1,010,099 | -11,111,089 |
