Answer:
360
Explanation:
The LCM of two (or more numbers) is the smallest common multiple of those numbers. One method to find the LCM is to take multiples of each number and take the multiple which is the smallest common multiple
The multiples of 60 and 72 are found as follows by multiplying each number by integers 1, 2, 3, 4, 5, 6, 7, 8 etc
Multiples of 60 ==> 60, 120, 180, 140, 360, 420, 480,....
Multiples of 72 ==> 72, 144, 216, 288, 360, 432, ...
The common smallest multiple of 60 and 72 is 360
So the LCM of 60 and 72 is 360
