- Almost_prime abstract "In number theory, a natural number is called k-almost prime if it has exactly k prime factors, counted with multiplicity. More formally, a number n is k-almost prime if and only if Ω(n) = k, where Ω(n) is the total number of primes in the prime factorization of n:A natural number is thus prime if and only if it is 1-almost prime, and semiprime if and only if it is 2-almost prime. The set of k-almost primes is usually denoted by Pk. The smallest k-almost prime is 2k. The first few k-almost primes are:The number πk(n) of positive integers less than or equal to n with at most k prime divisors (not necessarily distinct) is asymptotic to: a result of Landau. See also the Hardy–Ramanujan theorem.".
