2 and 5
Twenty is composite. It has the factors 1, 2, 4 ,5, 10, and 20. Prime numbers have exactly two factors. Composite numbers have three or more.
Prime numbers have only two factors whereas composite numbers have more than two factors

Yes, all prime numbers have only two factors
Prime numbers have two factors.

Prime factors of numbers are small numbers that the bigger (original) number can divide by. The prime factors have to be prime. This means they only have two factors, itself and one.
Because square numbers have more than two factors whereas prime numbers have only two factors
Any two prime numbers will be relatively prime. Numbers are relatively prime if they do not have any prime factors in common. Prime numbers have only themselves as prime factors, so all prime numbers are relatively prime to the others.
