263. Ugly Number

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.

My code:

class Solution(object):    def isUgly(self, num):        """        :type num: int        :rtype: bool        """        if num ==1:            return True        if num<=0:            return False        while num % 2 ==0:            num = num/2        while num % 3 ==0:            num =num/3        while num % 5 ==0:            num =num5

        return num ==1

or 

    def isUgly0(self, num):        """        :type num: int        :rtype: bool        """        if num<=0:            return False        if num ==0:            return True        for i in 2,3,5:            while num% i ==0:                num =num/i        return num ==1
