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 14,511,665, 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 | 14,511,665 | |
| -1 | -14,511,665 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 14,511,665.
Example:
1 x 14,511,665 = 14,511,665
and
-1 x -14,511,665 = 14,511,665
Notice both answers equal 14,511,665
With that explanation out of the way, let's continue. Next, we take the number 14,511,665 and divide it by 2:
14,511,665 ÷ 2 = 7,255,832.5
If the quotient is a whole number, then 2 and 7,255,832.5 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 | 14,511,665 | |
| -1 | -14,511,665 |
Now, we try dividing 14,511,665 by 3:
14,511,665 ÷ 3 = 4,837,221.6667
If the quotient is a whole number, then 3 and 4,837,221.6667 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 | 14,511,665 | |
| -1 | -14,511,665 |
Let's try dividing by 4:
14,511,665 ÷ 4 = 3,627,916.25
If the quotient is a whole number, then 4 and 3,627,916.25 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 | 14,511,665 | |
| -1 | 14,511,665 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 53 | 265 | 371 | 1,855 | 7,823 | 39,115 | 54,761 | 273,805 | 414,619 | 2,073,095 | 2,902,333 | 14,511,665 |
| -1 | -5 | -7 | -35 | -53 | -265 | -371 | -1,855 | -7,823 | -39,115 | -54,761 | -273,805 | -414,619 | -2,073,095 | -2,902,333 | -14,511,665 |
