class Function { 
  String PrimeTime(int num) {
    for (int i = 2; i < num; i++) {
      if (num%i == 0) {
        return "false";
      }
    }
      
    return "true";
   
  }
 
  public static void main (String[] args) { 
    // keep this function call here    
    Scanner  s = new Scanner(System.in);
    Function c = new Function();
    System.out.print(c.PrimeTime(s.nextLine()));
  }
