#2229

Ionel are de rezolvat mai multe probleme de divizibilitate. Unele dintre ele îi cer să afle câte numere au anumite proprietăţi. Vă rugăm să-l ajutaţi să termine tema mai repede. Scrieţi un program care citeşte un număr natural n şi două numere prime u şi v mai mici decât 10 şi determină câte numere naturale mai mici sau egale cu n au proprietatea că nu sunt divizibile nici cu u, nici cu v.
