Binary Operation using LCM 📺 Watch Video Explanation: Determine whether the operation is a binary operation or not Given: Set \( S = \{1,2,3,4,5\} \) and operation defined by \( a * b = \mathrm{LCM}(a,b) \) Concept: A binary operation must satisfy the closure property, i.e., the result must belong to the same set. Solution:
