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 12,442,339, 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 | 12,442,339 | |
| -1 | -12,442,339 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,442,339.
Example:
1 x 12,442,339 = 12,442,339
and
-1 x -12,442,339 = 12,442,339
Notice both answers equal 12,442,339
With that explanation out of the way, let's continue. Next, we take the number 12,442,339 and divide it by 2:
12,442,339 ÷ 2 = 6,221,169.5
If the quotient is a whole number, then 2 and 6,221,169.5 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 | 12,442,339 | |
| -1 | -12,442,339 |
Now, we try dividing 12,442,339 by 3:
12,442,339 ÷ 3 = 4,147,446.3333
If the quotient is a whole number, then 3 and 4,147,446.3333 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 | 12,442,339 | |
| -1 | -12,442,339 |
Let's try dividing by 4:
12,442,339 ÷ 4 = 3,110,584.75
If the quotient is a whole number, then 4 and 3,110,584.75 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 | 12,442,339 | |
| -1 | 12,442,339 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 73 | 91 | 511 | 949 | 1,873 | 6,643 | 13,111 | 24,349 | 136,729 | 170,443 | 957,103 | 1,777,477 | 12,442,339 |
| -1 | -7 | -13 | -73 | -91 | -511 | -949 | -1,873 | -6,643 | -13,111 | -24,349 | -136,729 | -170,443 | -957,103 | -1,777,477 | -12,442,339 |
