Cody Problem 45251 asked us to find the last non-zero digit in a factorial. For this problem consider the primorial
#, the product of primes up to and including the nth prime
. For example, for n = 12, the primorial is 7420738134810, whose last non-zero digit is 1.
Find the last non-zero digit in the primorial
#.
