我这代码为什么不行呢？

import java.util.Scanner;
public class Main {

    public static void main(String[] args) {
        // TODO Auto-generated method stub
        Scanner in=new Scanner(System.in);

        int m1=in.nextInt();
        int m2=in.nextInt();
        int m3=in.nextInt();

        int f=0;

        for(int a=123;a<999;a++){
            int b=a/m1*m2;
            int c=a/m1*m3;
            if(b>=999||c>=999)break;
                    String a1=String.valueOf(a);
                    String b1=String.valueOf(b);
                    String c1=String.valueOf(c);

                    if(a>b||a>c||b>c)break;
                    if(pd(a1,b1,c1)){
                        if(hj(a,b,c).equals(hj(m1,m2,m3))){
                            f=1;
                            System.out.println(a+" "+b+" "+c);
                        }
                    }

        }
        if(f==0){
            System.out.println("No!!!");
        }

    }

    private static String hj(int a, int b, int c) {
        // TODO Auto-generated method stub
        for(int i=a;i>=2;i--){

                b=b/i;
                c=c/i;
            }
        }
        return String.valueOf(a)+String.valueOf(b)+String.valueOf(c);
    }

    private static boolean pd(String a1, String b1, String c1) {
        // TODO Auto-generated method stub
        String s=a1+b1+c1;

        for(char i='1';i<='9';i++){
            if(s.contains(String.valueOf(i))==false){
                return false;
            }
        }
        return true;
    }

}
