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 12,443,459, 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 | 12,443,459 | |
| -1 | -12,443,459 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,443,459.
Example:
1 x 12,443,459 = 12,443,459
and
-1 x -12,443,459 = 12,443,459
Notice both answers equal 12,443,459
With that explanation out of the way, let's continue. Next, we take the number 12,443,459 and divide it by 2:
12,443,459 ÷ 2 = 6,221,729.5
If the quotient is a whole number, then 2 and 6,221,729.5 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 | 12,443,459 | |
| -1 | -12,443,459 |
Now, we try dividing 12,443,459 by 3:
12,443,459 ÷ 3 = 4,147,819.6667
If the quotient is a whole number, then 3 and 4,147,819.6667 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 | 12,443,459 | |
| -1 | -12,443,459 |
Let's try dividing by 4:
12,443,459 ÷ 4 = 3,110,864.75
If the quotient is a whole number, then 4 and 3,110,864.75 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 | 12,443,459 | |
| -1 | 12,443,459 |
If you did it right, you will end up with this table:
| 1 | 7 | 41 | 191 | 227 | 287 | 1,337 | 1,589 | 7,831 | 9,307 | 43,357 | 54,817 | 65,149 | 303,499 | 1,777,637 | 12,443,459 |
| -1 | -7 | -41 | -191 | -227 | -287 | -1,337 | -1,589 | -7,831 | -9,307 | -43,357 | -54,817 | -65,149 | -303,499 | -1,777,637 | -12,443,459 |
