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 16,066,715, 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 | 16,066,715 | |
| -1 | -16,066,715 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 16,066,715.
Example:
1 x 16,066,715 = 16,066,715
and
-1 x -16,066,715 = 16,066,715
Notice both answers equal 16,066,715
With that explanation out of the way, let's continue. Next, we take the number 16,066,715 and divide it by 2:
16,066,715 ÷ 2 = 8,033,357.5
If the quotient is a whole number, then 2 and 8,033,357.5 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 | 16,066,715 | |
| -1 | -16,066,715 |
Now, we try dividing 16,066,715 by 3:
16,066,715 ÷ 3 = 5,355,571.6667
If the quotient is a whole number, then 3 and 5,355,571.6667 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 | 16,066,715 | |
| -1 | -16,066,715 |
Let's try dividing by 4:
16,066,715 ÷ 4 = 4,016,678.75
If the quotient is a whole number, then 4 and 4,016,678.75 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 | 16,066,715 | |
| -1 | 16,066,715 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 47 | 235 | 329 | 1,645 | 9,767 | 48,835 | 68,369 | 341,845 | 459,049 | 2,295,245 | 3,213,343 | 16,066,715 |
| -1 | -5 | -7 | -35 | -47 | -235 | -329 | -1,645 | -9,767 | -48,835 | -68,369 | -341,845 | -459,049 | -2,295,245 | -3,213,343 | -16,066,715 |
