What is the difference between a prime number and relatively prime numbers?
Prime numbers are those which are divisible only by 1 and the number itself... Example: 7 is divisible by no number other than 7 and 1. Relatively prime numbers are those pairs of numbers which have no common divisor other than one. Example: (15,16) Factors of 15:1,3,5,15 Factors of 16:1,4,16 Common factor of 15 & 16 is 1, hence 15 & 16 are relatively prime.
