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 11,522,555, 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 | 11,522,555 | |
| -1 | -11,522,555 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 11,522,555.
Example:
1 x 11,522,555 = 11,522,555
and
-1 x -11,522,555 = 11,522,555
Notice both answers equal 11,522,555
With that explanation out of the way, let's continue. Next, we take the number 11,522,555 and divide it by 2:
11,522,555 ÷ 2 = 5,761,277.5
If the quotient is a whole number, then 2 and 5,761,277.5 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 | 11,522,555 | |
| -1 | -11,522,555 |
Now, we try dividing 11,522,555 by 3:
11,522,555 ÷ 3 = 3,840,851.6667
If the quotient is a whole number, then 3 and 3,840,851.6667 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 | 11,522,555 | |
| -1 | -11,522,555 |
Let's try dividing by 4:
11,522,555 ÷ 4 = 2,880,638.75
If the quotient is a whole number, then 4 and 2,880,638.75 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 | 11,522,555 | |
| -1 | 11,522,555 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 383 | 547 | 1,915 | 2,735 | 4,213 | 6,017 | 21,065 | 30,085 | 209,501 | 1,047,505 | 2,304,511 | 11,522,555 |
| -1 | -5 | -11 | -55 | -383 | -547 | -1,915 | -2,735 | -4,213 | -6,017 | -21,065 | -30,085 | -209,501 | -1,047,505 | -2,304,511 | -11,522,555 |
