A Harshad number, also called a Niven number, is an integer that is divisible by the sum of its own digits when written in a given base. Because the condition depends on the digit representation, a number can be a Harshad number in one base while failing to be one in another. The concept was defined by the Indian mathematician D. R. Kaprekar, and the name Harshad derives from Sanskrit words meaning joy-giver.

Is Kind Of Object
Entity-backed identity for the object-kind enum value this mathematical object already carries, resolved to a mathematics concept by an explicit value-to-entity map (phase 3 bucket conversion, docs\design_entity_backed_browse_buckets_20260928.md). The object-kind fact itself stays on the object unchanged.
