Let A = {2,3,4,6,8,12,24,48} and denote the partial order of divisibility Let B = {4,6,12}. Select the correct least upper bounds of B. Select one: a. None b. 48 c24 d.12

Step 1
In a partially ordered set, an element 'u' is said to be an upper bound of a subset 'B' if every element in 'B' is less than or equal to 'u'. The least upper bound is the smallest of these upper bounds. Show more…
