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,
