%N A141813 Primitive RMS numbers: RMS numbers which are not the product of two smaller 
               RMS numbers.
%C A141813 RMS numbers (see A140480) are numbers such that the RMS (Root Mean Square) 
               of their divisors is an integer. If A and B both appear in A140480 
               and GCD(A,B)=1, then A*B is also in A140480. This sequence contains 
               only those RMS numbers that are not a product smaller RMS numbers.
%e A141813 The RMS Number 287 is not in the sequence because 287=7*41 and both 7 
               and 41 are RMS numbers.
