      Question

      The H.C.F of two numbers is 3 and their L.C.M is 782. If

      one of the numbers is 34, find the other?
      A 38 Correct Answer Incorrect Answer
      B 56 Correct Answer Incorrect Answer
      C 69 Correct Answer Incorrect Answer
      D 71 Correct Answer Incorrect Answer

      Solution

      HCF = 3, LCM = 782, a = 34 & b = ? So as we know that a × b = HCF× LCM or 34 × b = 3 × 782 or b = 3 × 782/34 = 2346/34 = 69.
