Let $N$ be the minimum value of $x + y$ over all ordered pairs $(x, y)$ of positive integers such that $xy = 25000000$. Let $a = 9$ and $b = 22$. Define $r$ to be the number of positive integers $n$ such that $1 \leq n \leq N$, $a$ divides $n$, and $\gcd(n, b) = 1$. Compute $r + 2^r \bmod 56162$, where the exponent is ...
