    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 15, 20, 30 = 60

    Therefore, the smallest number which is divisible by 15, 20, and 30 is 60.
