• Fortunate number
  • … and the least \(m>1\) making the sum prime is 19, because smaller offsets fail and \(510529\) is prime. to If a Fortunate number had a prime divisor at most \(p_n\), that divisor would divide both the primorial and the offset and hence the candidate sum, contradicting its primality. demonstrates that continuity.
