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 12,339,535, 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 | 12,339,535 | |
| -1 | -12,339,535 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,339,535.
Example:
1 x 12,339,535 = 12,339,535
and
-1 x -12,339,535 = 12,339,535
Notice both answers equal 12,339,535
With that explanation out of the way, let's continue. Next, we take the number 12,339,535 and divide it by 2:
12,339,535 ÷ 2 = 6,169,767.5
If the quotient is a whole number, then 2 and 6,169,767.5 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 | 12,339,535 | |
| -1 | -12,339,535 |
Now, we try dividing 12,339,535 by 3:
12,339,535 ÷ 3 = 4,113,178.3333
If the quotient is a whole number, then 3 and 4,113,178.3333 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 | 12,339,535 | |
| -1 | -12,339,535 |
Let's try dividing by 4:
12,339,535 ÷ 4 = 3,084,883.75
If the quotient is a whole number, then 4 and 3,084,883.75 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 | 12,339,535 | |
| -1 | 12,339,535 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 17 | 65 | 85 | 169 | 221 | 845 | 859 | 1,105 | 2,873 | 4,295 | 11,167 | 14,365 | 14,603 | 55,835 | 73,015 | 145,171 | 189,839 | 725,855 | 949,195 | 2,467,907 | 12,339,535 |
| -1 | -5 | -13 | -17 | -65 | -85 | -169 | -221 | -845 | -859 | -1,105 | -2,873 | -4,295 | -11,167 | -14,365 | -14,603 | -55,835 | -73,015 | -145,171 | -189,839 | -725,855 | -949,195 | -2,467,907 | -12,339,535 |
