Question

1 p
Let A = { 1,2,3,4,12} and partial
order on A be divisibility. Then
least upper bound of 2&3 is
O 1
O 2
O 4
O 12​

Answer 1

Step-by-step explanation:

– According to above given question first, we have to find the poset for the divisibility.

Let the set is A.

A={(3

12), (3

24), (3

48), (3

72), (4

12), (4

24), (4

48), (4

72), (12

24), (12

48), (12

72), (24

48), (24

72)}

So, now the Hasse diagram will be:
