We deny the premise. 60 is not a prime number.
15 is a factor of 60.The proof: 15 x 4=60(It is, of course, not a prime factor.)
30 has three prime numbers and is a factor of 60.
5 + 2 = 7

No, 60 and 75 are not relatively prime because their greatest common factor is 15 and not 1. In order for them to be relatively prime, 1 must be their greatest common factor.
