relatively prime
     
         Having no common divisors (greater than 1).
     
        Two numbers are said to be relativey prime if there is no
        number greater than unity that divides both of them evenly.
     
        For example, 10 and 33 are relativly prime.  15 and 33 are not
        relatively prime, since 3 is a {divisor} of both.
