How do you write a program to read two integers and print the greater common divisor?

Answer 1

#include<stdio.h>

int gcd (int a, int b) {

if (a==0) return b;

if (b==0) return a;

return a<b ? gcd (a, b%a) : gcd (b, a%b);

}

int main (void) {

int a, b;

printf ("Enter two integers: ")

scanf ("%d\n", &a);

scanf ("%d\n", &b);

printf ("The GCD of %d and %d is %d\n", a, b, gcd (a, b));

return 0;

}
