Problem Statement

You are given integers NN and MM.

Consider a sequence aa of length NN consisting of positive integers such that a1+a2+...+aNa_1 + a_2 + ... + a_N = MM. Find the maximum possible value of the greatest common divisor of a1,a2,...,aNa_1, a_2, ..., a_N.

Constraints

  • All values in input are integers.
  • 1N1051 \leq N \leq 10^5
  • NM109N \leq M \leq 10^9

Input

Input is given from Standard Input in the following format:

NN MM

Output

Print the maximum possible value of the greatest common divisor of a sequence a1,a2,...,aNa_1, a_2, ..., a_N that satisfies the condition.

2

Consider the sequence (a1,a2,a3)=(2,4,8)(a_1, a_2, a_3) = (2, 4, 8). Their greatest common divisor is 22, and this is the maximum value.
