Question
What is the smallest positive number which is divisible by
9, 18, and 27?Solution
ATQ,
We know, the smallest number which can be divisible by 'a', 'b', and 'c' = LCM of 'a', 'b', and 'c'.
Here, 'a', 'b', and 'c' are three different numbers.
Required number = LCM of 9, 18, 27 = 54
Therefore, the smallest number which is divisible by 9, 18, and 27 is 54.
