What is the LCM of 280 and 180 - Find out answer step by step

Definition of LCM

LCM stands for least common multiple. In mathematics, LCM of two numbers 280 and 180, is defined as the smallest positive integer that is divisible by both. It is written as LCM(280, 180).

Properties of LCM

The LCM of two given numbers is never less than any of those numbers. Eg- LCM of 280 and 180 is 2520, where 280 and 180 are less than 2520.
LCM is associative which means LCM(280, 180) = LCM(180, 280).
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.

Both the cricket team and the rugby team had games, today. The cricket team plays every 280 days and the basketball team plays every 180 days. When will both teams have games on the same day again?

Given that the cricket team plays every 280 days and the basketball team plays every 180 days, so for finding the next time when both teams will play again we need to find the LCM of 280 and 180.
So, LCM of 280 and 180 is 2520.

Sammy's company prints 280 textbooks at a time. Daniel's company prints textbooks in sets of 180 at a time. According to a survey done by a committee, both companies printed the same number of textbooks last year. Find the least number of books that each company would have printed.

To find the least number of textbooks that each company could have printed we need to find the LCM of 280 and 180.
So, LCM of 280 and 180 is 2520.

Ariel exercises every 280 days and Rubel every 180 days. They both excercised today. How many days will it be until they excercise together again?

The problem can be solved using LCM, because we are trying to figure out the least time until they excercise together again.
So, LCM of 280 and 180 is 2520.

What is the relation between LCM and GCF( Greatest Common Factor)?

Greatest common factors or gcf of 280 and 180 is GCF(280, 180) * LCM(280, 180) = (280 x 180) / GCF(280, 180) = 2520.
