    Question

    The LCM of two natural numbers is 8 times their HCF. If

    the product of given two numbers is 1152, then find the LCM of the numbers. 
    A 96 Correct Answer Incorrect Answer
    B 12 Correct Answer Incorrect Answer
    C 144 Correct Answer Incorrect Answer
    D 24 Correct Answer Incorrect Answer

    Solution

    Let the HCF of the number be 'H'.  So, LCM = 8H  Product of two numbers = Product of their HCF and LCM  So, 8H × H = 1152  Or, H² = 144  Or, H = 12 or H = –12  Since, HCF cannot be negative. So, H = 12  Therefore, LCM = 8 × 12 = 96
