The LCM is #120#.

Explanation:

LCM means least common multiple.

We can use prime factorization of each given number to determine the LCM.

#6:# #2xxcolor(red)3#

#8:# #color(green)2xxcolor(green)2xxcolor(green)2#

#5:# #color(blue)5#

Multiply each factor the maximum times it occurs in the three numbers.

#"LCM"=color(red)3xxcolor(green)2xxcolor(green)2xxcolor(green)2xxcolor(blue)5=120#
