## Description
|
||
|
|
<section id="description"> A função lcm (a, b) indica o menor múltiplo comum de a e b. Seja A (n) a média dos valores de lcm (n, i) para 1≤i≤n. Por exemplo: A (2) = (2 + 2) / 2 = 2 e A (10) = (10 + 10 + 30 + 20 + 10 + 30 + 70 + 40 + 90 + 10) / 10 = 32. <p> Seja S (n) = ∑A (k) para 1≤k≤n. S (100) = 122726. </p><p> Encontre S (99999999019) mod 999999017. </p></section>
