A problem came in my mind few days ago. And now I am very willing to know the ans. I tried but couldn't solve it.

You are given n numbers 1<= n <= (10^5) you have to minimize the gcd of those numbers.

You can do one operation : Replace a with a-1 (a is a number)

**Note: ** It is not a part of any ongoing contest.

Can any one please tell me any solution that will work in this time constraint. Thanks in advance.
