Question

How to know that we have to find LCM or HCF???? Plz help me, I am really confused.

Answer 1

Hey mate.


The HCF of two or more numbers is the largest common factor of the given numbers.

The LCM is the smallest number that is a common multiple of two or more numbers.

Answer 2

Step-by-step explanation:

It is actually quite tricky to figure it out,you need to have a very clear understanding of the basic concepts of L.C.M. and H.C.F.

L.C.M. is the least common multiple of two or more numbers which means that it gives the least number which is divisble with given numbers

H.C.F. is the highest common factor of two or more numbers which means that it is the biggest number which divides given numbers

Generally if the question has words like "least" or "smallest" then we have to find the L.C.M. and when there are words like "greatest" or "biggest" then we have to find H.C.F.

However this is not always the case.
