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 11,111,135, 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 | 11,111,135 | |
| -1 | -11,111,135 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 11,111,135.
Example:
1 x 11,111,135 = 11,111,135
and
-1 x -11,111,135 = 11,111,135
Notice both answers equal 11,111,135
With that explanation out of the way, let's continue. Next, we take the number 11,111,135 and divide it by 2:
11,111,135 ÷ 2 = 5,555,567.5
If the quotient is a whole number, then 2 and 5,555,567.5 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 | 11,111,135 | |
| -1 | -11,111,135 |
Now, we try dividing 11,111,135 by 3:
11,111,135 ÷ 3 = 3,703,711.6667
If the quotient is a whole number, then 3 and 3,703,711.6667 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 | 11,111,135 | |
| -1 | -11,111,135 |
Let's try dividing by 4:
11,111,135 ÷ 4 = 2,777,783.75
If the quotient is a whole number, then 4 and 2,777,783.75 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 | 11,111,135 | |
| -1 | 11,111,135 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 523 | 607 | 2,615 | 3,035 | 3,661 | 4,249 | 18,305 | 21,245 | 317,461 | 1,587,305 | 2,222,227 | 11,111,135 |
| -1 | -5 | -7 | -35 | -523 | -607 | -2,615 | -3,035 | -3,661 | -4,249 | -18,305 | -21,245 | -317,461 | -1,587,305 | -2,222,227 | -11,111,135 |
