The LCM is $120$ .

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.

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