Someone actually printed the largest known prime number in a book! That's over 41 MILLION digits! Imagine the poor printer that had to spit out this mathematical monstrosity! The number is so massive it would take you approximately 45 days to read aloud if you didn't sleep, eat, or question your life choices. And the best part? By the time you finish reading this book, mathematicians will probably discover an even larger prime, making your coffee table decoration instantly obsolete. It's the mathematical equivalent of buying an iPhone right before the new model drops!
