Expert Answer:

To know whether to find h.c.f. or l.c.m. first read the question carefully and look for what quantities are to be determined.

If the problem asks for maximum things, like find the maximum numbers of rooms required, greatest size of a measuring can, etc., then find HCF.

If the problem asks for simultaneous reoccurrence of events then find LCM.
