What is the minimum quorum (minyan) required to recite Kaddish, Kedushah, and Barchu?
Synopsis
All authorities require a minyan of ten adult free Jewish males for any davar shebikdushah. The Talmudic derivation is from 'ונקדשתי בתוך בני ישראל' via a gezerah shavah connecting 'toch' to the ten spies.
