"When the integers a and b are coprime, the standard way of expressing this fact in mathematical notation is to indicate that their greatest common divisor is one, by the formula gcd(a, b) = 1 or (a, b) = 1. In their 1989 textbook Concrete Mathematics, Ronald Graham, Donald Knuth, and Oren Patashnik proposed an alternative notation to indicate that a and b are relatively prime and that the term "prime" be used instead of coprime (as in a is prime to b).

For example: (11, 13) Here, 11 and 13 are coprime numbers, and their LCM is 11 × 13 = 143. Because prime numbers only share one common factor, 1, any two prime numbers are always coprime. So, are all prime numbers coprime? Yes! For example: (11, 13), (17, 19)
