#2336

Dorel are o nouă pasiune, să coloreze divizorii unui număr natural. Primind cadou de ziua lui un număr natural n, s-a gândit să coloreze toate numerele naturale de la 1 la n cu câte o culoare, astfel încât toţi divizorii proprii ai unui număr să aibă aceeaşi culoare cu numărul. Vă roagă pe voi să aflaţi care este numărul maxim de culori care pot fi folosite.
