Explanation Group: Let S be any set, let ∘ be any operation, and let a , b , and c be any elements of S . We say that S is a group for the operation of ∘ if the following properties are satisfied: Closure property: ( a ∘ b ) ∈ S Associative property: ( a ∘ b ) ∘ c = a ∘ ( b ∘ c ) Identity property: There exists a number I ∈ S so that x ∘ I = I ∘ x = x for every x ∈ S . Inverse property: For each x ∈ S , there exists a corresponding x − 1 ∈ S so that x ∘ x − 1 = x − 1 ∘ x = I , where I is the identity element in S . Further, S is called a commutative group (or Abelian group) if the following property is satisfied: Commutative property: a ∘ b = b ∘ a Given: The set ℕ and a , b ∈ ℕ And also D be an operation defined by a D b = g.c.f. of a and b Now we have to find that whether it is a commutative group or not. We know that the set ℕ is the set of Natural numbers. So we take any two natural numbers and check the operation D satisfies all the properties. Closure property: If a , b ∈ ℕ then g.c.f. of a and b also belongs to ℕ . Therefore a D b ∈ ℕ which satisfies the closure property. For example: Let 6 , 9 ∈ ℕ . 3 6 2 2 1 3 9 3 3 1 The g.c.f. of 6 and 9 is 3 . Therefore a D b = 3 ∈ ℕ Hence it satisfies the closure property. Associative property: If a , b , c ∈ ℕ then g.c.f. of a , b , c will be same if we change the brackets also. (i.e.) ( a D b ) D c = a D ( b D c ) For example: Let 6 , 9 , 12 ∈ ℕ . L.H.S: 3 6 2 2 1 3 9 3 3 1 The g.c.f. of 6 and 9 is 3
