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 11,122,397, 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 | 11,122,397 | |
| -1 | -11,122,397 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 11,122,397.
Example:
1 x 11,122,397 = 11,122,397
and
-1 x -11,122,397 = 11,122,397
Notice both answers equal 11,122,397
With that explanation out of the way, let's continue. Next, we take the number 11,122,397 and divide it by 2:
11,122,397 ÷ 2 = 5,561,198.5
If the quotient is a whole number, then 2 and 5,561,198.5 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 | 11,122,397 | |
| -1 | -11,122,397 |
Now, we try dividing 11,122,397 by 3:
11,122,397 ÷ 3 = 3,707,465.6667
If the quotient is a whole number, then 3 and 3,707,465.6667 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 | 11,122,397 | |
| -1 | -11,122,397 |
Let's try dividing by 4:
11,122,397 ÷ 4 = 2,780,599.25
If the quotient is a whole number, then 4 and 2,780,599.25 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 | 11,122,397 | |
| -1 | 11,122,397 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 31 | 143 | 169 | 193 | 341 | 403 | 1,859 | 2,123 | 2,509 | 4,433 | 5,239 | 5,983 | 27,599 | 32,617 | 57,629 | 65,813 | 77,779 | 358,787 | 855,569 | 1,011,127 | 11,122,397 |
| -1 | -11 | -13 | -31 | -143 | -169 | -193 | -341 | -403 | -1,859 | -2,123 | -2,509 | -4,433 | -5,239 | -5,983 | -27,599 | -32,617 | -57,629 | -65,813 | -77,779 | -358,787 | -855,569 | -1,011,127 | -11,122,397 |
