The LCM of 20 and 40 is 40. Since 40 is a factor of 20, it is the LCM of the set.

The LCM of 20 and 40 can be found by taking the highest prime powers of the numbers i.e. 20= 2^2 x 5 , 40= 2^3 x 5 ----> Therefore, the highest power of prime powers here between 2^2 and 2^3 is 2^3, and between 5 and 5, 5 is the highest

This means that the LCM = 2^3 x 5 = 40 The LCM of 20 and 40 is 40.
