... 5 x 3 x 5). It can be the product of a twin primes pair with itself and another prime or primes (e.g., 3 x 5 x 3 x 5 x 23 x 89). It can be the product of a twin primes pair with another twin primes pair or other twin primes pairs (e.g., 11 x 13 x 227 x 229 x 461 x 463) It can be the product of a tw ...

... since a polynomial equation of degree less than p−1 cannot have p−1 roots in Zp . *Theorem: Let p be a prime. There there is an integer t such that ordp (t) = p−1. That is, there exists a primitive root modulo p. If we factorize p − 1 as q1n1 q2n2 · · · qrnr , where the qi are distinct primes, then ...

On the Product of Divisors of $n$ and of $sigma (n)
... that t > 1, for otherwise the number n will be of the form n = q α for some prime number q and some positive integer α, and the contradiction comes from the fact that σ(q α ) is coprime to q. We now note that it is not possible that the prime factors of n are in {2, 3}. Indeed, if this were so, then ...
