A composer writes a piece using rhythmic units of lengths that are powers of $6$, specifically $6^0$, $6^1$, and $6^2$, since $\binom{13}{13} = 1$ and the sum starts at $k = 0$. The total duration of the piece is $n = 6^0 + 6^1 + 6^2$. The musician then explores all possible ways to subdivide this total duration into a...

Let $m = 13$. Let $k_0$ be the minimum value of $x + y$ over all pairs of positive integers $(x, y)$ such that $xy = 142884$. Let $n$ be the smallest positive integer such that the largest power of $13$ dividing $n!$ is at least $k_0$. Define $S = \sum_{d \mid n} \phi(d)$, where $\phi$ denotes Euler's totient function....
