$97$ is the largest prime less than $100$. What is the largest prime factor of $97!$ (97 factorial)?  (Reminder: The number $n!$ is the product of the integers from 1 to $n$.  For example, $5!=5\cdot 4\cdot3\cdot2\cdot 1= 120$.)
So, I want to find the largest prime number that is less than or equal to $97$. Well, that's easy, it's just $97$ itself, since $97$ is the largest prime less than $100$. So, the largest prime factor of $97!$ is $97$.
