#include <bits/stdc++.h>
using namespace std;
typedef long long ll;

ll gcd(ll a, ll b)

    if (b == 0)
        return a;
    return gcd(b, a % b);
}

int main()
{
    int n;
    cin >> n;
    while (n--)

        ll T, a, b;
        cin >> T;
        a = sqrt(2 * T), b = a + 1;
        double da = a, db = b, aa, ab;
        aa = (da - 1) / 2 + (double)T / da;
        ab = (db - 1) / 2 + (double)T / db;
        if (ab < aa)
            a = b;
        ll g = gcd(a * a - a + 2 * n, 2 * a);
