Code explained in video :

1. GCD


  main(){
      int n1,n2,i,gcd;
      printf("enter two numbers");
      scanf("%d %d",&n1 , &n2);
      for (int i = 1; i<=n1 && i<=n2; i++)
      {
          if (n1%i == 0 && n2%i == 0)
          {
              gcd = i;
          }
      }
      printf("gcd of %d and %d is %d\n",n1,n2,gcd);
      getch();
  }

2. LCM


main(){
int n1,n2,i,gcd,lcm;
printf("enter two numbers");
scanf("%d %d",&n1 , &n2);
for (int i = 1; i<=n1 && i<=n2; i++)
{
    if (n1%i == 0 && n2%i == 0)
    {
        gcd = i;
    }
}
lcm = (n1*n2)/gcd;
printf("lcm of %d and %d is %d\n",n1,n2,lcm);
getch()}
