If aa and bb are any two positive integers, then: (A) HCF (a,b)(a, b) + LCM (a,b)=a+b(a, b) = a + b (B) HCF (a,b)(a, b) + LCM (a,b)=a×b(a, b) = a \times b (C) HCF (a,b)×(a, b) \times LCM (a,b)=a×b(a, b) = a \times b (D) HCF (a,b)=(a, b) = LCM (a,b)(a, b)

  1. A.

    HCF (a, b) + LCM (a, b) = a + b

  2. B.

    HCF (a, b) + LCM (a, b) = a × b

  3. C.

    HCF (a, b) × LCM (a, b) = a × b

  4. D.

    HCF (a, b) = LCM (a, b)
