      1337, leaving remainder 7 in each case?
      A 45 Correct Answer Incorrect Answer
      B 90 Correct Answer Incorrect Answer
      C 65 Correct Answer Incorrect Answer
      D 70 Correct Answer Incorrect Answer

      Solution

      Subtract the common remainder 7 from both numbers: 917 - 7 = 910 1337 - 7 = 1330 Now find HCF of 910 and 1330. 1330 - 910 = 420 910 = 420 x 2 + 70 420 = 70 x 6 So HCF = 70
