GCD function for C

Question

Q 1. Problem 5 (evenly divisible) I tried the brute force method but it took time, so I referred few sites and found this code:

#include
int gcd(i         


        

Answer 1

I executed this statements for GCD :

#include
#include
int main(){
   int l, s,r;

   printf("\n\tEnter value : ");
   scanf("%d %d",&l,&s);

  while(l%s!=0){
    r=l%s;
    l=s;
    s=r;
  }
  printf("\n\tGCD = %d",s);
  getch();
}
