What is LCM of 320 and 283?


Definition of LCM

LCM stands for least common multiple. In mathematics, LCM of two numbers 320 and 283, is defined as the smallest positive integer that is divisible by both. It is written as LCM(320, 283).

Properties of LCM

  • The LCM of two given numbers is never less than any of those numbers. Eg- LCM of 320 and 283 is 90560, where 320 and 283 are less than 90560.
  • LCM is associative which means LCM(320, 283) = LCM(283, 320).
  • 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 or more prime numbers is their product.

Examples

Franky and Joy are running on a circular track. They start at the same time. They take 320 and 283 minutes respectively to go round once. Find at what time they will run together?

Franky and Joy are running on a circular track. They take 320 and 283 minutes respectively to go round once. We need to find out at what time (minimum) they will run together again. For this we need to find the LCM of 320 and 283.
So, LCM of 320 and 283 is 90560.

A shopkeeper sells candies in packet of 320 and chocolates in packet of 283. What is the least number of candies and chocolates Annie should buy so that there will be one candy for each chocolate?

The least number of candies and chocolates Annie should buy so that there will be one candy for each chocolate we need to find the lcm of 320 and 283.
So, LCM of 320 and 283 is 90560.

Both the cricket team and the rugby team had games, today. The cricket team plays every 320 days and the basketball team plays every 283 days. When will both teams have games on the same day again?

Given that the cricket team plays every 320 days and the basketball team plays every 283 days, so for finding the next time when both teams will play again we need to find the LCM of 320 and 283.
So, LCM of 320 and 283 is 90560.
