NO!!!! By the fact that it is an EVEN number, it is a compound number number, with a factor of '2'. . Since it is a factored compound number , then it is NOT a prime number. NB. Except for '2'. there are no EVEN prime numbers. All Prime numbers are ODD. However, not all odd numbers are prime number. Here is a list of number to '20'. 1,2,3,4,**5,**6,7,8,9,10,11,12,13,14,15,16,17,18,19,& 20 2,3,5,7,11,13,17, 19 Are prime numbers. This leaves 9,15, which are ODD numbers, but NOT Prime numbers, because ;- 3 x 3 = 9 and 3 x 5 = 15 are compound odd numbers. NB The list of numbers and prime numbers beyond '20' is inexhaustive.
