Python3 one liner
The minimum difference that can be created by manipulating two numbers in a way given by the question is equal to the greatest common divisor of the two numbers
The minimum difference that can be created by manipulating two numbers in a way given by the question is equal to the greatest common divisor of the two numbers. \n\nFor example : \n```\nnums = [12,18]\ngcd(12,18) = 6\n```\nTherefore the minimum difference after manipulating the numbers would be 6.\n\nFor this problem, we need to find whether the gcd of any two numbers in `nums`  is 1\n--> gcd(nums) == 1\n\n**Python3 One Liner:**\n```\nclass Solution:\n    def isGoodArray(self, nums: List[int]) -> bool:\n        return reduce(gcd,nums) == 1\n```
