APMO 2016 No 2 - Bilangan keren

Recommended Posts

Sebuah bilangan bulat positif disebut keren jika bilangan tersebut dapat diekspresikan dalam bentuk $$2^{a_1}+2^{a_2}+...+2^{a_{100}}$$ dimana $a_1,a_2,...,a_{100}$ adalah bilangan bulat nonnegatif yang tidak harus berbeda.

Tentukan $n$ terkecil sehingga tidak ada kelipatan $n$ yang keren.
