If aa and bb are any two positive integers, then:

  1. A.

    HCF(a,b)+LCM(a,b)=a+b\text{HCF}(a, b) + \text{LCM}(a, b) = a + b

  2. B.

    HCF(a,b)+LCM(a,b)=a×b\text{HCF}(a, b) + \text{LCM}(a, b) = a \times b

  3. C.

    HCF(a,b)×LCM(a,b)=a×b\text{HCF}(a, b) \times \text{LCM}(a, b) = a \times b

  4. D.

    HCF(a,b)=LCM(a,b)\text{HCF}(a, b) = \text{LCM}(a, b)
