How to Determine whether to find HCF or LCM
Asked by | 6th Mar, 2009, 12:36: PM
Expert Answer:
Be careful in interpreting the word problem
Look for what quantities 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 we need to find HCF,
If the problem asks for simultaneous reoccurrence of events then it is LCM.
