What is LCM of 245 and 175?


Definition of LCM

LCM stands for least common multiple. In mathematics, LCM of two numbers 245 and 175, is defined as the smallest positive integer that is divisible by both. It is written as LCM(245, 175).

Properties of LCM

  • The LCM of two or more prime numbers is exactly equal to their product.
  • LCM is associative which means LCM(245, 175) = LCM(175, 245).
  • LCM is commutative which means LCM(a, b, c) = LCM(LCM(a, b), c) = LCM(a, LCM(b, c)).
  • LCM is distributive, which means LCM(ab, bc, ad) = d * LCM(x, y, z).
  • The LCM of two given numbers is always greater than the given numbers numbers. Eg- LCM of 245 and 175 is 1225, where 1225 is greater than 245 and 175.
