## Description
|
|
<section id="description"> Un entero se llama B-suave si ninguno de sus factores primos es mayor que B. <p> Sea SB (n) el divisor B-smooth más grande de n. Ejemplos: S1 (10) = 1 S4 (2100) = 12 S17 (2496144) = 5712 </p><p> Defina F (n) = ∑1≤B≤n ∑0≤r≤n SB (C (n, r)). Aquí, C (n, r) denota el coeficiente binomial. Ejemplos: F (11) = 3132 F (1 111) mod 1 000 000 993 = 706036312 F (111 111) mod 1 000 000 993 = 22156169 </p><p> Encontrar F (11 111 111) mod 1 000 000 993. </p></section>
