A positive integer having such property is what I define as Hardy-Ramanujan-ish Harshad Number, for the purpose of this post. (There might be a technical term for it, but I couldn't find it)

A positive integer having such property is what I define as Hardy-Ramanujan-ish Harshad Number, for the purpose of this post. (There might be a technical term for it, but I couldn't find it, unless it's member of A110921)

Note that only four Hardy-Ramanujan-ish Harshad Numbers exist (1,81,1458 and 1729), but you must not write code which checks for equivalence with them.
