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 14,120,315, 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 | 14,120,315 | |
| -1 | -14,120,315 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 14,120,315.
Example:
1 x 14,120,315 = 14,120,315
and
-1 x -14,120,315 = 14,120,315
Notice both answers equal 14,120,315
With that explanation out of the way, let's continue. Next, we take the number 14,120,315 and divide it by 2:
14,120,315 ÷ 2 = 7,060,157.5
If the quotient is a whole number, then 2 and 7,060,157.5 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 | 14,120,315 | |
| -1 | -14,120,315 |
Now, we try dividing 14,120,315 by 3:
14,120,315 ÷ 3 = 4,706,771.6667
If the quotient is a whole number, then 3 and 4,706,771.6667 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 | 14,120,315 | |
| -1 | -14,120,315 |
Let's try dividing by 4:
14,120,315 ÷ 4 = 3,530,078.75
If the quotient is a whole number, then 4 and 3,530,078.75 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 | 14,120,315 | |
| -1 | 14,120,315 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 139 | 695 | 1,529 | 1,847 | 7,645 | 9,235 | 20,317 | 101,585 | 256,733 | 1,283,665 | 2,824,063 | 14,120,315 |
| -1 | -5 | -11 | -55 | -139 | -695 | -1,529 | -1,847 | -7,645 | -9,235 | -20,317 | -101,585 | -256,733 | -1,283,665 | -2,824,063 | -14,120,315 |
