Solution Method
Answer :

LCM ( Least Common Multiple)

Full form of LCM is "Lowest Common Multiple " or sometime referred to as "Least Common Multiple". The LCM of two or more numbers is the smallest number that is divisible by all numbers in the set.

For example LCM of 2 and 5 is 10. 10 is the lowest positive number which is divisible by both 5 and 2. So LCM of 2 and 5 is 10.

Methods to Find LCM

There are various methods to find the LCM of two or numbers. These are-

  • Listing Multiples
  • Prime Factorization
  • Cake/Ladder Method
  • Division Method
  • Using the Greatest Common Factor GCF
  • Venn Diagram

Properties of LCM

  • The LCM is associative:
    LCM(p,q ) = LCM(q, p)
  • The LCM is commutative:
    LCM(p, q, r) = LCM(LCM(p, q), r) = LCM(p, LCM(q, r))
  • The LCM is distributive:
    LCM(da, db, dc) = d *LCM(a, b, c)
  • The LCM is related to the greatest common factor (GCF) :
    LCM(a,b) = (a × b) / GCF(a,b)
    GCF(a,b) = (a × b) / LCM(a,b)

How to use LCM Calculator ?
