How to find the LCM (least common multiple) of two numbers

Step-by-step explanation:

The L.C.M of any numbers can be obtained by using two methods and they are :

Prime Factorization method Division method

The steps for finding L.C.M of the given numbers by prime factorization method are mentioned below :

First of all , find the prime factors of each numbers.Take out the common prime factors.Also take out the other remaining prime factors.Multiply those all prime factors and obtain L.C.M if there is not any common prime factors , then their L.C.M is the product of the given numbers..

The steps for finding L.C.M of the given numbers by division method are mentioned below :

Arrange the given numbers in horizontal position.Thus , arranged numbers should be divided by a prime number. During this process , that prime number should divide any two or more given numbers.Repeat the process till you get prime number as quotient for each number.The product of all prime factors and last quotients is L.C.M

( According to me , Prime factorization method is kinda easy )

Example : L.C.M of 20 and 24

20 = 2 × 2 × 5

24 = 2 × 2 × 2 × 3

L.C.M = Common factors × Remaining factors

= 2 × 2 × 5 × 2 × 3

=
