If any element in the array changes, the complete data structure has to be recomputed. … WebJun 24, 2012 · The greatest common divisor (GCD) of a and b is the largest number that divides both of them with no remainder. One way to find the GCD of two numbers is Euclid’s algorithm, which is based on the observation that if r is the remainder when a is divided by b, then gcd (a, b) = gcd (b, r). As a base case, we can use gcd (a, 0) = a.
