#include<iostream>
using namespace std;
int a[5],b[5],c[5];
int q,w,e,ppt = 1;
int main()
{
    cin >> q >> w >> e;
    for(int i = 123;i <= 999; i++)
    {
        a[1] = i / 100;
        a[2] = i / 10 % 10;
        a[3] = i % 100 % 10;
        b[1] = i / q * w / 100;
        b[2] = i / q * w / 10 % 10;
        b[3] = i / q * w % 100 % 10;
        c[1] = i / q * e / 100;
        c[2] = i / q * e / 10 % 10;
        c[3] = i / q * e % 100 % 10;
        if(a[1] + a[2] + a[3] + b[1] + b[2] + b[3] + c[1] + c[2] + c[3] == 45 && a[1] * a[2] * a[3] * b[1] * b[2] * b[3] * c[1] * c[2] * c[3] == 362880)
        {
            ppt = 0;
            cout << i << " " << i / q * w << " " << i / q * e << endl;
        }
    }
    if(ppt)
    {
        cout <<"NO!!!" <<endl;
    }
    return 0;
}
