If d(x) denotes the no. positive divisors of x and d(d(d(x))), d(d(x)), d(x) and x can be arranged in 12 different ways. Find possible values of n(x), where n(x) is no. of prime factors of x. Also find possible values of x less than 100.

By x is prime factor of A, it is meant that x is prime and x is a divisor of A. Check this
http://en.wikipedia.org/wiki/Prime_factor. Sorry, for not giving u the definition.\
For example, prime factors for 12 are 2 and 3 only.
