Answer 1

Answer:

Cited by 1 — Since 2. √ n + 1 is a positive integer, we may write. 4(n + 1) = b2, so that b must be even. ... prime factor p of n distinct from 3 contributes p2 − 1 to the factor σ(p)φ(p) of σ(n)φ(n). So ... If n = pq is a product of distinct primes, then σ(n) + φ(n)=(p + 1)(q +1)+(p − ... of n are both primes or n = p3 for some prime p and a + d. 2.
