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 14,505,865, 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 | 14,505,865 | |
| -1 | -14,505,865 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 14,505,865.
Example:
1 x 14,505,865 = 14,505,865
and
-1 x -14,505,865 = 14,505,865
Notice both answers equal 14,505,865
With that explanation out of the way, let's continue. Next, we take the number 14,505,865 and divide it by 2:
14,505,865 ÷ 2 = 7,252,932.5
If the quotient is a whole number, then 2 and 7,252,932.5 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 | 14,505,865 | |
| -1 | -14,505,865 |
Now, we try dividing 14,505,865 by 3:
14,505,865 ÷ 3 = 4,835,288.3333
If the quotient is a whole number, then 3 and 4,835,288.3333 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 | 14,505,865 | |
| -1 | -14,505,865 |
Let's try dividing by 4:
14,505,865 ÷ 4 = 3,626,466.25
If the quotient is a whole number, then 4 and 3,626,466.25 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 | 14,505,865 | |
| -1 | 14,505,865 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 97 | 485 | 1,067 | 2,719 | 5,335 | 13,595 | 29,909 | 149,545 | 263,743 | 1,318,715 | 2,901,173 | 14,505,865 |
| -1 | -5 | -11 | -55 | -97 | -485 | -1,067 | -2,719 | -5,335 | -13,595 | -29,909 | -149,545 | -263,743 | -1,318,715 | -2,901,173 | -14,505,865 |
