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 14,160,065, 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 | 14,160,065 | |
| -1 | -14,160,065 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 14,160,065.
Example:
1 x 14,160,065 = 14,160,065
and
-1 x -14,160,065 = 14,160,065
Notice both answers equal 14,160,065
With that explanation out of the way, let's continue. Next, we take the number 14,160,065 and divide it by 2:
14,160,065 ÷ 2 = 7,080,032.5
If the quotient is a whole number, then 2 and 7,080,032.5 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 | 14,160,065 | |
| -1 | -14,160,065 |
Now, we try dividing 14,160,065 by 3:
14,160,065 ÷ 3 = 4,720,021.6667
If the quotient is a whole number, then 3 and 4,720,021.6667 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 | 14,160,065 | |
| -1 | -14,160,065 |
Let's try dividing by 4:
14,160,065 ÷ 4 = 3,540,016.25
If the quotient is a whole number, then 4 and 3,540,016.25 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 | 14,160,065 | |
| -1 | 14,160,065 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 23 | 85 | 115 | 391 | 1,955 | 7,243 | 36,215 | 123,131 | 166,589 | 615,655 | 832,945 | 2,832,013 | 14,160,065 |
| -1 | -5 | -17 | -23 | -85 | -115 | -391 | -1,955 | -7,243 | -36,215 | -123,131 | -166,589 | -615,655 | -832,945 | -2,832,013 | -14,160,065 |
