java三个数求最大公约数和最小公倍数

  Scanner scan = new Scanner(System.in);
	System.out.println("请依次输入三个数字:");
	int a = scan.nextInt();
	int b = scan.nextInt();
	int c = scan.nextInt();
	int z = a > b ? b : a;
	int d = c > z ? z : c;	
	for(int i = d ;; i--) {
		if(a % i == 0 && b % i == 0 && c % i ==0) {
			System.out.println("最大公约数为" + i);
			break;
		}			
	}
	 z = a < b ? b : a;
	 d = c < z ? z : c;
	 for(int i = d; ;i++) {
		 if(i % a == 0 && i % b == 0 && i % c == 0) {
			 System.out.println("最小公倍数为" + i);
			 break;
		 }
	 }
