A puzzle game has levels numbered from $2$ to $8$. A level is unlocked only if its number is prime. The final challenge uses the factorial of the highest unlocked level number, $n!$, where $n$ is the largest prime between $2$ and $8$. Let $M = n!$. What is the remainder when $55849M$ is divided by $54195$?
