Expert Answer:

In order to  find out if one need to take out H.C.F. OR L.C.M in a problem we need to analyse the problem.

In the problems asking for common things HCF will be rquired, example a tape required to measure the height of students, vessel required to measure milk etc

LCM is required when simultaneous occurence of events is to be found.
