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 14,501,015, 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 | 14,501,015 | |
| -1 | -14,501,015 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 14,501,015.
Example:
1 x 14,501,015 = 14,501,015
and
-1 x -14,501,015 = 14,501,015
Notice both answers equal 14,501,015
With that explanation out of the way, let's continue. Next, we take the number 14,501,015 and divide it by 2:
14,501,015 ÷ 2 = 7,250,507.5
If the quotient is a whole number, then 2 and 7,250,507.5 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 | 14,501,015 | |
| -1 | -14,501,015 |
Now, we try dividing 14,501,015 by 3:
14,501,015 ÷ 3 = 4,833,671.6667
If the quotient is a whole number, then 3 and 4,833,671.6667 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 | 14,501,015 | |
| -1 | -14,501,015 |
Let's try dividing by 4:
14,501,015 ÷ 4 = 3,625,253.75
If the quotient is a whole number, then 4 and 3,625,253.75 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 | 14,501,015 | |
| -1 | 14,501,015 |
If you did it right, you will end up with this table:
| 1 | 5 | 29 | 97 | 145 | 485 | 1,031 | 2,813 | 5,155 | 14,065 | 29,899 | 100,007 | 149,495 | 500,035 | 2,900,203 | 14,501,015 |
| -1 | -5 | -29 | -97 | -145 | -485 | -1,031 | -2,813 | -5,155 | -14,065 | -29,899 | -100,007 | -149,495 | -500,035 | -2,900,203 | -14,501,015 |
