%N a(n) is the least number m such that the arithmetic mean of the distinct primes dividing m equals n.

%C Are there any terms with more than 3 prime factors?

%H Paolo P. Lava, <a href="/A082572/b082572.txt">Table of n, a(n) for n = 2..1000</a>

%e a(6) = 35 because the prime factors of 35 are {5, 7}, which have mean 6.

%Y Cf. A070009, A078177, A200612.

%K easy,nonn
