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 14,430,515, 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 | 14,430,515 | |
| -1 | -14,430,515 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 14,430,515.
Example:
1 x 14,430,515 = 14,430,515
and
-1 x -14,430,515 = 14,430,515
Notice both answers equal 14,430,515
With that explanation out of the way, let's continue. Next, we take the number 14,430,515 and divide it by 2:
14,430,515 ÷ 2 = 7,215,257.5
If the quotient is a whole number, then 2 and 7,215,257.5 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 | 14,430,515 | |
| -1 | -14,430,515 |
Now, we try dividing 14,430,515 by 3:
14,430,515 ÷ 3 = 4,810,171.6667
If the quotient is a whole number, then 3 and 4,810,171.6667 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 | 14,430,515 | |
| -1 | -14,430,515 |
Let's try dividing by 4:
14,430,515 ÷ 4 = 3,607,628.75
If the quotient is a whole number, then 4 and 3,607,628.75 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 | 14,430,515 | |
| -1 | 14,430,515 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 59 | 295 | 649 | 3,245 | 4,447 | 22,235 | 48,917 | 244,585 | 262,373 | 1,311,865 | 2,886,103 | 14,430,515 |
| -1 | -5 | -11 | -55 | -59 | -295 | -649 | -3,245 | -4,447 | -22,235 | -48,917 | -244,585 | -262,373 | -1,311,865 | -2,886,103 | -14,430,515 |
