C#

The program should direct the user to input two numbers: MIN and MAX (MIN <= MAX). Starting with the number MIN and ending with the number MAX, in ascending order, create an output line listing its prime factors in ascending order, each preceded by a colon. Skip the lines starting with the prime numbers. Below is an example of the output for MIN = 6 and MAX = 9.

6:2:3

8:2:2:2

9:3:3

MIN = 8; MAX = 8 is a valid input resulting in a single line as output. MIN = 11; MAX = 11 will result in no output.

You should not pre-populate your program with a table of prime factors.
