    Question

    The product of the two prime numbers is 187. What will

    the L.C.M of these two numbers?
    A 187 Correct Answer Incorrect Answer
    B 107 Correct Answer Incorrect Answer
    C 197 Correct Answer Incorrect Answer
    D 177 Correct Answer Incorrect Answer

    Solution

    We know that, If there are two numbers a and b, Then, a × b = LCM of (a, b) × HCF of (a, b) According to the question a × b = 187 And we know that HCF for two prime numbers is = 1 So,   187 = LCM of (a, b) × 1 ⇒ LCM of (a, b) = 187
