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 14,212,255, 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 | 14,212,255 | |
| -1 | -14,212,255 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 14,212,255.
Example:
1 x 14,212,255 = 14,212,255
and
-1 x -14,212,255 = 14,212,255
Notice both answers equal 14,212,255
With that explanation out of the way, let's continue. Next, we take the number 14,212,255 and divide it by 2:
14,212,255 ÷ 2 = 7,106,127.5
If the quotient is a whole number, then 2 and 7,106,127.5 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 | 14,212,255 | |
| -1 | -14,212,255 |
Now, we try dividing 14,212,255 by 3:
14,212,255 ÷ 3 = 4,737,418.3333
If the quotient is a whole number, then 3 and 4,737,418.3333 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 | 14,212,255 | |
| -1 | -14,212,255 |
Let's try dividing by 4:
14,212,255 ÷ 4 = 3,553,063.75
If the quotient is a whole number, then 4 and 3,553,063.75 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 | 14,212,255 | |
| -1 | 14,212,255 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 37 | 85 | 185 | 629 | 3,145 | 4,519 | 22,595 | 76,823 | 167,203 | 384,115 | 836,015 | 2,842,451 | 14,212,255 |
| -1 | -5 | -17 | -37 | -85 | -185 | -629 | -3,145 | -4,519 | -22,595 | -76,823 | -167,203 | -384,115 | -836,015 | -2,842,451 | -14,212,255 |
