Answer: The only even prime number is 2.
A prime number has exactly two factors and is a positive integer. If p is a prime number, then 1 and p themselves are only necessary factors. Any number that does not obey this is called composite numbers.
Properties of prime numbers
A few of the prime numbers’ features are:
- It is possible to divide any number greater than 1 by at least one prime number.
- It is possible to express any positive integer greater than 2 as the sum of two prime numbers.
- All other prime numbers, except 2, are odd. That is we can assume that 2 is the only number that is even prime number.
- Two prime numbers are always coprime to one another.
