Problem Statement

You are given integers N and M.

Consider a sequence a of length N consisting of positive integers such that a_1 + a_2 + ... + a_N = M. Find the maximum possible value of the greatest common divisor of a_1, a_2, ..., a_N.

Constraints

All values in input are integers.

1 \leq N \leq 10^5

N \leq M \leq 10^9

Input

Input is given from Standard Input in the following format:

N M

Output

Print the maximum possible value of the greatest common divisor of a sequence a_1, a_2, ..., a_N that satisfies the condition.

Sample Input 1

3 14

Sample Output 1

2

Consider the sequence (a_1, a_2, a_3) = (2, 4, 8). Their greatest common divisor is 2, and this is the maximum value.

Sample Input 2

10 123

Sample Output 2

3

Sample Input 3

100000 1000000000

Sample Output 3

10000

Solution in Python (2.7.6) (judge verdict: Wrong Answer)

N,M=map(int,raw_input().split())
F=[]
i=1
while i * i <= M:
    if M%i==0:
        F.append(i)
        if i!=1 and i*i!=M: F.append(M/i)
    i+=1
F.sort()    
ans=-1
for k in F:
    if (M/k-N>=0):
        ans=k
print(ans)
