I SHOULD have included a comment that the 1 case is controversial. 
Someone might argue that, since 1 has no prime factors and therefore 
hasn't any (positive) prime-factorization exponents, then none of 1's 
prime-factorization exponents divide 1.
;)
(And so, technically, 1 meets the definition of the sequence....sort of..)


So I included the 1 in the event someone searching for this sequence on 
the OEIS includes a 1 at the beginning of the sequence they are searching 
for.


Thanks,
