What is the LCM of 12 and 210 - Find out answer step by step

How do we define LCM?

LCM, abbreviation for least common multiple, is defined as the smallest number that is the product of two or more numbers 12 and 210

Properties of LCM

The LCM of two given numbers is never less than any of those numbers. Eg- LCM of 12 and 210 is 420, where 12 and 210 are less than 420.
LCM is associative which means LCM(12, 210) = LCM(210, 12).
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.

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

Greatest common factors or gcf of 12 and 210 is GCF(12, 210) * LCM(12, 210) = (12 x 210) / GCF(12, 210) = 420.

Sammy's company prints 12 textbooks at a time. Daniel's company prints textbooks in sets of 210 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 12 and 210.
So, LCM of 12 and 210 is 420.
