Answer 1

You typed your question as if you're asking a search engine rather than a real person :-) Please elaborate. I'm guessing you want a C program that find least and greatest common denominator for a given number?

Answer 2

You will find out gcd by simple procedure. Subtract the small number from the greater number. Continue doing this untill youe two numbers are same or you get 1. In first case, the nmuber is your gcd, in second case, 1 is gcd.
Once you get gcd, finding lcd is one step.
number1 * number2/gcd will give you lcd.
