WebFeb 25, 2024 · GCD (Greatest common divisor) or HCF (Highest common factor) of two numbers is the largest positive integer that divides the two numbers without any remainder. Example: GCD (8,12) is 4 because 4 is the highest number which divides both the numbers i.e 8 and 12 completely.

The greatest common divisor (GCD) of two nonzero integers a and b is the greatest positive integer d such that d is a divisor of both a and b; that is, there are integers e and f such that a = de and b = df, and d is the largest such integer. The GCD of a and b is generally denoted gcd(a, b).. This definition also applies when one of a and b is …
