;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 '''.'''
'''2144''' is not prime; it would be shown as '''.'''
