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 11,661,055, 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 | 11,661,055 | |
| -1 | -11,661,055 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 11,661,055.
Example:
1 x 11,661,055 = 11,661,055
and
-1 x -11,661,055 = 11,661,055
Notice both answers equal 11,661,055
With that explanation out of the way, let's continue. Next, we take the number 11,661,055 and divide it by 2:
11,661,055 ÷ 2 = 5,830,527.5
If the quotient is a whole number, then 2 and 5,830,527.5 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 | 11,661,055 | |
| -1 | -11,661,055 |
Now, we try dividing 11,661,055 by 3:
11,661,055 ÷ 3 = 3,887,018.3333
If the quotient is a whole number, then 3 and 3,887,018.3333 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 | 11,661,055 | |
| -1 | -11,661,055 |
Let's try dividing by 4:
11,661,055 ÷ 4 = 2,915,263.75
If the quotient is a whole number, then 4 and 2,915,263.75 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 | 11,661,055 | |
| -1 | 11,661,055 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 59 | 295 | 413 | 2,065 | 5,647 | 28,235 | 39,529 | 197,645 | 333,173 | 1,665,865 | 2,332,211 | 11,661,055 |
| -1 | -5 | -7 | -35 | -59 | -295 | -413 | -2,065 | -5,647 | -28,235 | -39,529 | -197,645 | -333,173 | -1,665,865 | -2,332,211 | -11,661,055 |
