How do you find the Least common multiple of 27, 18?

##54##

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"##
