The largest natural number, n, that has the property of all of its coprimes also being prime (besides 1). That is to say, all numbers smaller than n and larger than 1 that only share a factor of 1 with n are primes.
30 (7, 11, 13, 17, 23, 29 all share no factors with 30 besides 1. And all of these are primes).
