;Task: Write a program which counts up from   '''1''',   displaying each number as the multiplication of its prime factors. For the purpose of this task,   '''1'''   (unity)   may be shown as itself. ;Example:       '''2'''   is prime,   so it would be shown as itself.
      '''6'''   is not prime;   it would be shown as   '''2\times3.'''
'''2144'''   is not prime;   it would be shown as   '''2\times2\times2\times2\times2\times67.''' ;Related tasks: *   [[prime decomposition]] *   [[factors of an integer]] *   [[Sieve of Eratosthenes]] *   [[primality by trial division]] *   [[factors of a Mersenne number]] *   [[trial factoring of a Mersenne number]] *   [[partition an integer X into N primes]]
