How do you explain HCF and LCM?
Ans:- At first I explain the full for of LCM(Least Common Multiple) and HCF (Highest Common Factor ) . Then I discuss need of LCM and HCF after that I will give some example.
formula of HCF and LCM
Formula for solving LCM and HCF problems:
Multiplication of Two numbers = (HCF of the two numbers) x (LCM of the two numbers)
Hence, HCF of Two numbers = multiplication of Two numbers/L.C.M of two numbers
LCM of two numbers = multiplication of Two numbers/H.C.F. of Two numbers
Division Method for LCM problems
Division Method is very easy, popular in mathematics. Let see the applying procedure....
Q. Find the LCM of 20 and 40.
Answer:-
Therefore the LCM of 20 and 40 is (2 x 2 x 5 x 1 x 2) =40
Solve using short tricks:-
Step 1 : find the greatest number from them.
Step2: check the greatest number is divicible by the another number if yes then greatest is LCM
According to this problem we can see 40 is a greatest number and 40 is divicible by 20 then then the answer is 40.
