WebProperties. Many properties of a natural number n can be seen or directly computed from the prime factorization of n.. The multiplicity of a prime factor p of n is the largest exponent … WebPROPOSITION 3. A Carmichael number has at least three prime factors. Proof. Suppose that n has two prime factors: n = pq, where p, q are prime and p > q. Then p−1 > q−1, so p−1 does not divide q−1. By Proposition 2, p−1 does not divide n−1. So n is not a Carmichael number. PROPOSITION 4. Suppose that n is a Carmichael number and ...
