Correct Answer: B
Solution :
It is clear from the problem that we have to find L.C.M. of 3, 4, 6, and 8. \[3\,\,\,\,\,\,\,\,\,=\,\,\,\,1\times 3\] \[4\,\,\,\,\,\,\,\,=\,\,\,\,2\times 2\] \[6\,\,\,\,\,\,\,\,=\,\,\,\,2\times 3\] \[8\,\,\,\,\,\,\,\,=\,\,\,\,2\times 2\times 2\] \[\therefore \] Required L.C.M. \[=2\times 2\times 2\times 3=24\] \[\therefore \] Required lowest number divisible by \[3,4,6\] and \[8=24\].
