What is LCM of 124 and 175?


What is LCM?

In mathematics, least common multiple, which is ordinarily reffered to as LCM is characterized as the smallest non-zero number which is divisible by both given numbers 124 and 175.

Properties of LCM

  • The LCM of two given numbers is never less than any of those numbers. Eg- LCM of 124 and 175 is 21700, where 124 and 175 are less than 21700.
  • LCM is associative which means LCM(124, 175) = LCM(175, 124).
  • 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 124 and 175 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 124 and 175 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 124 and 175.
So, LCM of 124 and 175 is 21700.

A shopkeeper sells candies in packet of 124 and chocolates in packet of 175. 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 124 and 175.

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

Greatest common factors or gcf of 124 and 175 is GCF(124, 175) * LCM(124, 175) = (124 x 175) / GCF(124, 175) = 21700.

Sammy's company prints 124 textbooks at a time. Daniel's company prints textbooks in sets of 175 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 124 and 175.
So, LCM of 124 and 175 is 21700.
