|
|
<section id='description'>
|
||
|
|
La función lcm (a, b) denota el mínimo común múltiplo de ay b.
|
||
|
|
Sea A (n) el promedio de los valores de mcm (n, i) para 1≤i≤n.
|
||
|
|
Por ejemplo: A (2) = (2 + 2) / 2 = 2 y A (10) = (10 + 10 + 30 + 20 + 10 + 30 + 70 + 40 + 90 + 10) / 10 = 32.
|
||
|
|
|
||
|
|
Sea S (n) = ∑A (k) para 1≤k≤n.
|
||
|
|
S (100) = 122726.
|
||
|
|
|
||
|
|
|
||
|
|
Encuentra S (99999999019) mod 999999017.
