WebJul 11, 2009 · To check if a number is ugly, divide the number by greatest divisible powers of 2, 3 and 5, if the number becomes 1 then it is an ugly number otherwise not. For example, let us see how to check for 300 is ugly or not. Greatest divisible power of 2 … Time Complexity: O(n). Auxiliary Space: O(1) We can also use the below … WebDec 13, 2024 · Approach: The idea is to use recursion to solve this problem and check if a number is divisible by 2, 3 or 5. If yes then divide the number by that and recursively check that a number is an ugly number or not. If at any time, there is no such divisor, then return false, else true. Below is the implementation of the above approach: C++.
