how to find LCM and HCF quickly | LCM and HCF shortcut tricks | least common multiple | Zero Math About video : in this video the LCM concept and the shortcut trick for finding the LCM is explained. The the prime factorization method for finding LCM is as follows : The lowest common multiple (LCM) of two or more given numbers is the least number which is exactly divisible by each of them. For example; Multiples of 12 are 12, 24, 36, 48, 60, 72, …….. Multiples of 18 are 18, 36, 54. 72, ........ Common multiples of 12 and 18 are 36, 72. ∴ Least Common Multiple (LCM) = 36 The prime factorization method for LCM calculation is time consuming.
