    Question

    LCM of two numbers is 18 times their HCF. The product of

    the numbers is 64800. What will be the maximum possible difference between the numbers?
    A 1578 Correct Answer Incorrect Answer
    B 1552 Correct Answer Incorrect Answer
    C 1020 Correct Answer Incorrect Answer
    D 1535 Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    ATQ, Let HCF of two numbers be β€˜x’ So, LCM of two numbers = 18 Γ— x = 18x Or, x Γ— 18x = 64800 Or, 18xΒ² = 64800 Or, xΒ² = 3600 Or, x = √3600 = 60 LCM of two numbers = 60 Γ— 18 = 1080 Let two numbers be β€˜60a’ and β€˜60b’, where β€˜a’ and β€˜b’ are co-prime numbers. So, 60ab = 1080 Or, a Γ— b = 18 So, when a = 1 and b = 18, then difference will be maximum Desired difference = 60 Γ— 18 – 60 Γ— 1 = 1020
