3 x 3 x 5 = 45
2 x 5 x 37 = 370
2 x 3 x 5 x 13 = 390
2 x 3 x 3 x 5 x 13 x 37 = 43290, the LCM
Method: Multiply them together.
Actually, there is no answer to this question. You must have a secific number(s) like 27 and 45, their Least Common Multiple(LCM) is 135 in the use of some methods; Listing method and the Factor tree Method. I know that these methods are the easy ways to get to the LCM, but there is much, much more easier, and that is ===> The decomposition method.! :D enjoy solving problems and thanks for reading.
That's known as the least common multiple, or LCM.
The LCM is 12.
It is: 30
The Least Common Multiple (LCM) of (12,18,20) is 180.
Use some method which you probably already learned, to find the least common multiple. All the other common multiples are multiples of this least common multiple, so you can multiply the least common multiple by 2, by 3, by 4, etc., to get additional common multiples.
The least common denominator is the least common multiple of the denominators.
The least common multiple of 14 and 27 is 378
It is a method of finding the LCM (Least Common Multiple) of 2 or more numbers. Suitably used for finding the least common denominator when adding/subtracting fractions.
