One possible way would be to create an array of counters whose stages map to
the primes. Then feed it a pulse train of n pulses. If none of the counters

any
end up with any remainder then the number shouldn't be prime.

no

Ooops. I typed exactly opposite of what I intended. I apologize for any
confusion.
If the i'th prime counter has no remainder it means that n is a integer
multiple of i.
We want a situation such that after n pulses none of the counters are zero.
If all have a remainder then n is prime.
