Thanks Bill. I liked it. Well, I made short work of the first and third question using a basic calculator. For the second question I pulled up a prime number program I wrote in BASIC in the ‘80s. For the readers, the ONLY permutation of those numbers that is a prime is 431, and that provides the “1” in the answer (which I figured out first). So that meant the final question has zeros in the circles. Back to BASIC for more programming fun… There are actually a bunch of values that are divisible by 12 that have zeros in those places, the lowest being 146007900 (which is 12 × 12167325). That’ll be $1M, please.
