Expert Answer:

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 it is LCM.
