WebJul 26, 2024 · We can also use the inbuilt GCD function C++, discussed in the 4th approach. Approach 1 - Prime Factorization method In this algorithm, we will find the common factors of both numbers and then return the product of the common factors as the GCD of the two numbers. Steps of the algorithm: Create a function gcd (), and pass two numbers to it. WebI use a lot standard c++ gcd function (__gcd (x, y)). But today, I learnt that on some compiler __gcd (0, 0) gives exception. (Maybe because 0 is divisible by any number?! ) Note for myself and everybody: While using __gcd we must carefully handle (0, 0) case or write own gcd.
