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 156 and 92.

Properties of LCM

  • The LCM of two given numbers is never less than any of those numbers. Eg- LCM of 156 and 92 is 3588, where 156 and 92 are less than 3588.
  • LCM is associative which means LCM(156, 92) = LCM(92, 156).
  • 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 156 and 92 is GCF(156, 92) * LCM(156, 92) = (156 x 92) / GCF(156, 92) = 3588.

Sammy's company prints 156 textbooks at a time. Daniel's company prints textbooks in sets of 92 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 156 and 92.
So, LCM of 156 and 92 is 3588.
