While some of us were learning the multiplication table, Bizon the Champion had fun in his own manner. Bizon the Champion painted an *n* × *m* multiplication table, where the element on the intersection of the *i*-th row and *j*-th column equals *i*·*j* (the rows and columns of the table are numbered starting from 1). Then he was asked: what number in the table is the *k*-th largest number? Bizon the Champion always answered correctly and immediately. Can you repeat his success?

Consider the given multiplication table. If you write out all *n*·*m* numbers from the table in the non-decreasing order, then the *k*-th number you write out is called the *k*-th largest number.

Input

The single line contains integers *n*, *m* and *k* (1 ≤ *n*, *m* ≤ 5·10^{5}; 1 ≤ *k* ≤ *n*·*m*).

Output

Print the *k*-th largest number in a *n* × *m* multiplication table.
