Primes in base twelve

A prime number is any number that has no divisors, i.e. no number lower than it will divide into it without leaving a remainder. For example, there are no even primes aside from two. Thus no primes over two end in 2, 4, 6, 8 or 0 in base ten.

Since base twelve has divisors 2, 3, 4 and 6 no primes ending in 2, 3, 4, 6, 8, 9 or A12 will appear. This leaves 1, 5, 7, B12.
