    If the HCF of three numbers 144, x and 192 is 12, then the number x cannot be

    A) 180                              

    B) 84      

    C) 60                                

    D) 48

    Correct Answer: D

    Solution :

    \[144=12\times 2\times 2\times 3\] \[192=12\times 2\times 2\times 2\times 2\] By taking option [d], \[48=12\times 2\times 2\] Hence, the value of x will not be 48 otherwise the HCF of given numbers becomes 48.
