A number that only has 1 and itself as factors is called a Prime number. Prime numbers are integers greater than 1 that cannot be formed by multiplying two smaller positive integers. They have exactly two distinct positive divisors: 1 and the number itself. Examples of prime numbers include 2, 3, 5, 7, 11, and so on.

Can a number be relatively prime to itself?
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.
