What is the best explanation you’ve heard for 1 not being a prime number? For me it’s “because it breaks everything in my programs since the loops won’t terminate” but that’s obtuse. “Because the God of math decrees it so!” is compelling, but shallow.
“it can only be divided by 1 distinct number” is contrived.
1 “feels” prime— it has the fewest factors. (Primeness being about NOT having factors) ruling it out for having too few? eh.
“it’s the zero of multiplication” is better… thoughts?
