How will we come to know when to do HCF or LCM in a problem?
Expert Reply
Here are a few tips to recognise what needs to be determined
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 find LCM.
