What is LCM of 2100 and 990?


Definition of LCM

LCM stands for least common multiple. In mathematics, LCM of two numbers 2100 and 990, is defined as the smallest positive integer that is divisible by both. It is written as LCM(2100, 990).

Properties of LCM

  • The LCM of two given numbers is never less than any of those numbers. Eg- LCM of 2100 and 990 is 69300, where 2100 and 990 are less than 69300.
  • LCM is associative which means LCM(2100, 990) = LCM(990, 2100).
  • 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

Ram and Deepika are running on a circular track. They start at the same time. They take 2100 and 990 minutes respectively to go round once. Find at what time they will run together?

Ram and Deepika are running on a circular track. They take 2100 and 990 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 2100 and 990.
So, LCM of 2100 and 990 is 69300.

A shopkeeper sells candies in packet of 2100 and chocolates in packet of 990. 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 2100 and 990.
So, LCM of 2100 and 990 is 69300.

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

Greatest common factors or gcf of 2100 and 990 is GCF(2100, 990) * LCM(2100, 990) = (2100 x 990) / GCF(2100, 990) = 69300.

Sammy's company prints 2100 textbooks at a time. Daniel's company prints textbooks in sets of 990 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 2100 and 990.
So, LCM of 2100 and 990 is 69300.

Mary exercises every 2100 days and Nikki every 990 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 2100 and 990 is 69300.
