GCD of two numbers
By jaigurudev, 10 years ago, In English

Can any help with an algo that is fast enough to calculate the gcd of two positive numbers. I think one good approach will be to use __gcd of C++ but it is inbuilt, i want to create my own function. Please help...

a recursive method will work perfectly

int gcd(int a, int b) { if (a == 0) return b; else return gcd (b % a, a); }
