WebHowever, for some problems, this method is not always the most efficient method. Efficiency might matter if your test is timed. For example, if one of two numbers is a multiple of the other number, then the LCM of the two numbers is the larger number (for example, because 24 is a multiple of 8, LCM(8,24) is 24). WebLEAST OR LOWEST COMMON MULTIPLE (LCM) The LCM of two or more numbers is the least number which is exactly divisible by both of them. Example, 15 is the least common multiple of 3 and 5. Because the multiple of 3 = 3, 6, 9, 12, 15, 18, 21, … The multiple of 5 = 5, 10, 15, 20, 25,… Methods of finding LCM of numbers 1. METHOD OF PRIME ...
