How do we define LCM?

LCM, abbreviation for least common multiple, is defined as the smallest number that is the product of two or more numbers 107 and 27

Properties of LCM

  • The LCM of two given numbers is never less than any of those numbers. Eg- LCM of 107 and 27 is 2889, where 107 and 27 are less than 2889.
  • LCM is commutative which means LCM(a, b, c) = LCM(LCM(a, b), c) = LCM(a, LCM(b, c)).
  • The LCM of two or more prime numbers is exactly equal to their product.
  • LCM is associative which means LCM(107, 27) = LCM(27, 107).
  • LCM is distributive, which means LCM(ab, bc, ad) = d * LCM(x, y, z).
