# Find Greatest Common Divisor of Array.

It's day 10.

**Problem of the day** - Find Greatest Common Divisor of Array

**Tag** - Easy

Problem is to find the greatest common divisor of maximum and minimum element of given array.

**Input:** nums = [2,5,6,9,10]
**Output:** 2
**Explanation:**
The smallest number in nums is 2.
The largest number in nums is 10.
The greatest common divisor of 2 and 10 is 2.

I didn't want to put much efforts in this.

Here is my code -

```
class Solution {public: int findGCD(vector<int>& nums) { int sm = nums[0]; int mx = nums[0];
for(auto x: nums) { sm = min(sm, x); mx = max(mx, x); }
return __gcd(sm,mx); }};
```

I know, this code can be improved. I am not in the right state of modify this, may be tomorrow!
