4. The gretest common divisor gcd(x,y) where gcd(x, y) = x, if y=0           

otherwise gcd(x, y) = gcd(y, x MOD y), if y > 0

Answer 1

CODE

===============

#include <stdio.h>

/**

* Function to find the GCD of two integers

* @param integers x and y

* returns the GCD of x and y

*/

int GCD(int x, int y) {

if (y == 0)

return x;

return GCD(y, x % y);

}

int main(void) {

printf("GCD of 10 and 15 is: %d", GCD(10, 15));

}
