WebGroups Definition A group consists of a set G and a binary operation that takes two group elements a,b ∈ G and maps them to another group element a b ∈ G such that the following conditions hold. a) (Associativity) For all a,b,c ∈ G one has (a b) c = a (b c). b) (Neutral element) There exists an element e ∈ G with a e = e a = a for all a ∈ G. c) (Inverse … Greatest common divisors can be computed by determining the prime factorizations of the two numbers and comparing factors. For example, to compute gcd(48, 180), we find the prime factorizations 48 = 2 · 3 and 180 = 2 · 3 · 5 ; the GCD is then 2 · 3 · 5 = 2 · 3 · 5 = 12, as shown in the Venn diagram. The corresponding LCM is then 2 · 3 · 5 = 2 · 3 · 5 = 720.
