Two number are said to be "relatively prime" if they have no common factors - of course, other than the trivial factor 1. Even a prime number is not "relatively prime" to itself, since the prime number itself is the common factor. For example, the common factor of 7 and 7 is 7. Thus, the only situation I can think of where a number has no common factor with itself is that the number is 1.
