What is the LCM of 136 and 420 - Find out answer step by step

What is LCM of two numbers?

In mathematics, least common multiple which is commonly known as LCM is defined as the smallest non-zero number which is divisible by both given numbers 136 and 420.

Properties of LCM

The LCM of two given numbers is never less than any of those numbers. Eg- LCM of 136 and 420 is 14280, where 136 and 420 are less than 14280.
LCM is associative which means LCM(136, 420) = LCM(420, 136).
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 136 days and the basketball team plays every 420 days. When will both teams have games on the same day again?

Given that the cricket team plays every 136 days and the basketball team plays every 420 days, so for finding the next time when both teams will play again we need to find the LCM of 136 and 420.
So, LCM of 136 and 420 is 14280.

Sammy's company prints 136 textbooks at a time. Daniel's company prints textbooks in sets of 420 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 136 and 420.
So, LCM of 136 and 420 is 14280.

Ariel exercises every 136 days and Rubel every 420 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 136 and 420 is 14280.

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

Greatest common factors or gcf of 136 and 420 is GCF(136, 420) * LCM(136, 420) = (136 x 420) / GCF(136, 420) = 14280.
