Answers
Answer:
The number which is the smallest as well as perfectly divisible by 3,6 and 9 is their LCM.
18 is the LCM of 3, 6, and 9
Step-by-step explanation:
Least Common Multiple is the smallest number in which the given numbers divide exactly.
We can find the LCM of the numbers in many ways the commonly used methods are listed below.
LCM of 3, 6, and 9 by Listing Method
In this method, we list the first few multiples of 3, 6, and 9 and identify the common multiples.
The least among the common multiples is the LCM of 3, 6, and 9
Answer:
18 is the LCM of 3, 6, and 9.
Step-by-step explanation:
Prime factorisation of 6 = 2 × 3
Prime factorisation of 9 = 3 × 3
Product of common factors = 3
Product of other factors = 2 × 3 = 6
LCM (6, 9) = 3 × 6 = 18
