Unfortunately, in accordance with math laws, non real, negative integers cannot be factored."Prime numbers are defined as all real, non negative integers who's only factors are that of "1" and itself. Composite numbers are defined as all real, non negative integers who's factors are all real, non negative integers other than "1" and itself.
No. "Natural numbers" only refers to integers greater or equal to zero, that is, non-negative integers.
