Let p1 = 2, p2 = 3, . . be the list of primes, in increasing order. consider products of the form (p1 × p2 × ·· ·× pn) + 1 (compare with the proof of corollary 1.3.4). show that this number is prime for n = 1, . . , 5. show that when n = 6 this number is not prime. [use your answer to exercise 1.3.1. a calculator will speed the work of checking divisibility.]
