120

Explanation:

To find LCM:

  • First we have to factorize the numbers,

  • Then, we take the factors that are not in common.

  • Finally we take the common factor that is raised to the highest power:

Factorizing the given numbers:
#8=2^3#
#6=2*3#
#15=5*3#

Then:
#L.C.M=2^3*3*5=120#

(The 3 is a common factor between 15 and 6 and is in both cases raised to the first power that is why it was only taken once).
