Homework Statement
Consider the following magma, S is not empty; P(S) is the power set.
(P(S), U)
Now, let A and B be in P(S).
What is the GCD of A and B?
Homework Equations
The Attempt at a Solution
If I choose a common divisor of A and B under unions, call it X, I get that X is a subset of A and B as the only requirement.
The only way I can interpret "GCD" is that X is the largest such set. Then X = (A intersect B.)
Agree?
