Write a script that calculates the common factors between 18 and 54. To find a common factor, you can use the modulo operator (%) to check whether a number can be evenly divided into both numbers. Hint, test will be something like 12 % 3 = 0 and 30 % 3 = 0 , the modulo gives you the remainder,if the remainder is zero then it is a factor. ie 10 and 30 are both divisible by 3. 4 is not a common factor because it does not divide evenly into both numbers. You will need a loop to complete this easily . Murach, Chapter 14, SQL
