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 14,266,615, 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 | 14,266,615 | |
| -1 | -14,266,615 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 14,266,615.
Example:
1 x 14,266,615 = 14,266,615
and
-1 x -14,266,615 = 14,266,615
Notice both answers equal 14,266,615
With that explanation out of the way, let's continue. Next, we take the number 14,266,615 and divide it by 2:
14,266,615 ÷ 2 = 7,133,307.5
If the quotient is a whole number, then 2 and 7,133,307.5 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 | 14,266,615 | |
| -1 | -14,266,615 |
Now, we try dividing 14,266,615 by 3:
14,266,615 ÷ 3 = 4,755,538.3333
If the quotient is a whole number, then 3 and 4,755,538.3333 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 | 14,266,615 | |
| -1 | -14,266,615 |
Let's try dividing by 4:
14,266,615 ÷ 4 = 3,566,653.75
If the quotient is a whole number, then 4 and 3,566,653.75 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 | 14,266,615 | |
| -1 | 14,266,615 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 47 | 55 | 235 | 517 | 2,585 | 5,519 | 27,595 | 60,709 | 259,393 | 303,545 | 1,296,965 | 2,853,323 | 14,266,615 |
| -1 | -5 | -11 | -47 | -55 | -235 | -517 | -2,585 | -5,519 | -27,595 | -60,709 | -259,393 | -303,545 | -1,296,965 | -2,853,323 | -14,266,615 |
