WebSep 14, 2024 · A greatest common divisor of a and b, denoted gcd (a, b), is a natural number d satisfying. d ∣ a and d ∣ b. if e ∈ N and e ∣ a and e ∣ b, then e ∣ d. If gcd (a, b) = 1, we say that a and b are relatively prime or coprime. Note: This formalizes the idea of greatest common factors that is introduced around sixth grade.
