    If HCF of 306 and 657 is 9, then their LCM is ..........

    A) 22338

    B) 23328

    C) 22833

    D) 33228

    Correct Answer: A

    Solution :

    We know that,
    \[LCM\text{ }\times \text{ }HCF\text{ }=\]Product of two numbers
    \[LCM\times 9=306\times 675\]
    \[LCM=\frac{306\times 675}{9}\]
    \[=34\times 657=22338\]
    \[\therefore \,\,\,LCM\]of 306 and 657 = 22338
