WebTheorem A finite abelian group G has an lcm-closed order set, i.e. with o ( X) = order of X X, Y ∈ G ⇒ ∃ Z ∈ G: o ( Z) = l c m ( o ( X), o ( Y)) Proof By induction on o ( X) o ( Y). If it is 1 then trivially Z = 1. Otherwise write o ( X) = A P, o ( Y) = B P ′, P ′ ∣ P = p m > 1, prime p coprime to A, B Then o ( X P) = A, o ( Y P ′) = B.

WebAbelian p group (corresponding to a p primary part of G) is the direct product of cyclic groups. We prove this by induction on the power m of the order pm of the p group. Assume that the result is true for m: Let P be an Abelian group of order pm+1 and Q a subgroup of P of order pm (such Q exists by Sylow’s theorem). hilda acevedoWebJun 4, 2024 · Suppose that we wish to classify all abelian groups of order 540 = 2 2 ⋅ 3 3 ⋅ 5.
