Welcome to this week’s challenge problem (the third of the series). Though it looks terribly daunting it can be solved relatively quickly. That’s often the case with the GRE: a seemingly inscrutable problem that looks like it’ll take weeks to solve can be unlocked very quickly, if you follow the right path.
To make things even more fun with this question, I’ve made it a Numeric Entry. So no lucky guesses—but good luck anyway!
n = (61!+60!+59!)/3^x, what is greatest value of x where n is an integer?
