#### Explanation:

One way of finding the lowest common multiple ( LCM ) is.

#•" Divide the larger number by the smaller number"#

#•" If it divides exactly then larger number is LCM"#

#•" If not then repeat with multiples of larger number"#

#rArr27÷18" or " 27/18larr" does not divide exactly"# Now we try

#27xx2=54#

#rArr54/18=3larr" divides exactly"#

#" Hence 54 is the LCM of 27 and 18"#
