Write a program to check whether a given number is an ugly number.

Ugly numbers are positive numbers whose prime factors only include `2, 3, 5`

. For example, `6, 8`

are ugly while `14`

is not ugly since it includes another prime factor `7`

.

Note that `1`

is typically treated as an ugly number.

class Solution(object): def isUgly(self, number): if number == 1: return True if number == 0: return False while(number % 2 == 0): number /= 2 while(number % 3 == 0): number /= 3 while(number % 5 == 0): number /= 5 return number == 1
