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 14,445,515, 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 | 14,445,515 | |
| -1 | -14,445,515 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 14,445,515.
Example:
1 x 14,445,515 = 14,445,515
and
-1 x -14,445,515 = 14,445,515
Notice both answers equal 14,445,515
With that explanation out of the way, let's continue. Next, we take the number 14,445,515 and divide it by 2:
14,445,515 ÷ 2 = 7,222,757.5
If the quotient is a whole number, then 2 and 7,222,757.5 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 | 14,445,515 | |
| -1 | -14,445,515 |
Now, we try dividing 14,445,515 by 3:
14,445,515 ÷ 3 = 4,815,171.6667
If the quotient is a whole number, then 3 and 4,815,171.6667 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 | 14,445,515 | |
| -1 | -14,445,515 |
Let's try dividing by 4:
14,445,515 ÷ 4 = 3,611,378.75
If the quotient is a whole number, then 4 and 3,611,378.75 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 | 14,445,515 | |
| -1 | 14,445,515 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 389 | 1,061 | 1,945 | 2,723 | 5,305 | 7,427 | 13,615 | 37,135 | 412,729 | 2,063,645 | 2,889,103 | 14,445,515 |
| -1 | -5 | -7 | -35 | -389 | -1,061 | -1,945 | -2,723 | -5,305 | -7,427 | -13,615 | -37,135 | -412,729 | -2,063,645 | -2,889,103 | -14,445,515 |
