How do you memorise prime numbers?

There are infinitely many prime numbers so it is impossible to memorise them. Prime numbers do not follow any simple rule so it is not possible to memorise them by learning a rule either. Your best bet is to use them often so that you become familiar with them and so will recognise them. Also, learn the factorisation of odd numbers - since after 2, you need not bother with even numbers.
