    The product of HCF and LCM of 60, 84 and 108 is:      

    A) 55360

    B) 35360

    C) 45500

    D) 45360

    Correct Answer: D

    Solution :

    Sol.     \[HCF\,\,(60,84,108)=12\]
    and \[LCM\,\,(60,84,108)=3780\]
    \[\therefore \,\,\,\,\,HCF\times LCM=12\times 3780=45360\]
    So, option [d] is correct.
