A statistician first counts how many prime numbers $n_2$ lie between $2$ and $389$ inclusive, and calls this count $N$. Then they look at all integers $n_1$ between $1$ and $N$ that are multiples of $77$, and sum them to obtain $S$. They define $k$ to be the smallest positive integer that evenly divides this sum $S$. ...
