GCD The Largest

Given N, print the largest number that can be achieved by taking gcd (greatest common divisor) of any two i and j where i ̸= j and 1 ≤ i,j ≤ N. Input First line of input will contain the number of test cases, T ≤ 2000. Then T cases follow. For each case, there is a line containing one integer N where 2 ≤ N ≤ 1018. Output For each case, print one line containing a single integer which is the largest gcd of all pairs of numbers between 1 to N. Output Explanation In the second case the GCD table is: Here the largest gcd of all pairs of numbers between 1 to 5 is 2. Sample Input 2 2 5 Sample Output 1 2
