Exponential Towers

The number 729 can be written as a power in several ways: 36, 93 and 272. It can be written as 7291, of course, but that does not count as a power. We want to go some steps further. To do so, it is convenient to use ‘^’ for exponentiation, so we define a^b = ab. The number 256 then can be also written as 2^2^3, or as 4^2^2. Recall that ‘^’ is right associative, so 2^2^3 means 2^(2^3). We define a tower of powers of height k to be an expression of the form a1^a2^a3^ ...^ak, with k >1, and integers ai > 1. Given a tower of powers of height 3, representing some integer n, how many towers of powers of height at least 3 represent n? Input The input file contains several test cases, each on a separate line. Each test case has the form a^b^c, where a, b and c are integers, 1 < a,b,c ≤ 9585. Output For each test case, print the number of ways the number n = a^b^c can be represented as a tower of powers of height at least three. The magic number 9585 is carefully chosen such that the output is always less than 263. Sample Input 4^2^2 8^12^2 8192^8192^8192 2^900^576 Sample Output 2 10 1258112 342025379
