                Given that H.C.F. (306, 954, 1314) = 18, find L.C.M. (306, 954, 1314).           

    A) 1183234         

    B) 1123238      

    C)         1183914     

    D)         1123328                    

    Correct Answer: C

    Solution :

    LCM  \[(306,\,954,\,1314)=\] \[\frac{306\times 954\times 1314.HCF\,(306,954,1314)}{HCF\,(306,954)\times HCF(954,1314)\times HCF(306,1314)}\] \[=\frac{306\times 954\times 1314\times 18}{18\times 18\times 18}=1183914\]
