C++ :

#include <bits/stdc++.h>
using namespace std;

bool pd(int a[]){
	for(int i = 0;i < 10;i++){
		if(a[i] > 1){
			return false;
			break;
		}
	}
	
	if(a[0] != 0){
		return false;
	}else{
		return true;
	}
}

void chai(int n,int a[]){
	while(n != 0){
		a[n%10]++;
		n = n / 10;
	}
}

int main(){
	int i,j,k;
	int a[10] = {0};
	for(i = 100;i <= 999;i++){
		chai(i,a);
		if(pd(a)){
			j = i * 2;
			k = i * 3;
			chai(j,a);
			chai(k,a);
			if(pd(a)){
				cout<<i<<" "<<j<<" "<<k<<endl;
			}
		}
		
		memset(a,0,sizeof(a));
	}
}

Python :

a=[]
for i in range(123,330):
    b=2*i
    c=3*i
    a=list(str(i)+str(b)+str(c))
    f=0
    for j in range(9):
        for k in range(j+1,9):
            if(a[j]==a[k] or a[j]=="0"):
                f=1
                break
    if(f==0):
        print(i,b,c)
