What is the LCM of ##31z^3##, ##93z^2##?

##93z^3##
The LCM (Least Common Multiple) is the smallest value which each of two (or more) values divide evenly into.
Dividing ##31z^2## and ##93z^3## into factors and selecting all factors that are required by at least one of the two values:
##{:(31z^3,” = “, ,31, z, z, z),
(93z^2,” = “,3,31, z,z, ),(“required factors:”, ,3, 31, z, z, z)
:}##
The required factors of the LCM of ##31z^3## and ##93z^2## are
##3xx31xxzxxzxxz##
##rArr LCM(31z^3,93z^2) = 93z^3##
