What is the BIGGEST number that evenly divides 54 and 96?


How about 6?


54/6 = 9


96/6 = 16


Yes, that's correct.


The least common multiple (LCM) of two numbers is the smallest number (not including zero) that is a multiple of both.


Multiples of 3O: 30, 60, 90, 120, 150, 180, 210


Multiples of 42: 42, 84, 126, 168, 210


On the list provided, what number is found in both?


The number 210 is found in both.


Then 210 is the LCM.
