2 is the only even prime number, defined as a natural number greater than 1 that has no divisors other than 1 and itself. It is greater than 1 and has exactly two distinct positive divisors: 1 and 2. All other even numbers are divisible by 2, which disqualifies them from being prime. Therefore, 2 stands alone as the sole even prime number.

Well, there's your problem! You cannot "equate prime number with odd numbers". For one thing, the odd number, 9, is NOT prime!RTCNTC said:I know that 2 is an even number. I equate prime numbers with odd numbers.
Do you know what prime numbers are? What is your definition of "prime number"?Why is 2 a prime number when it is listed in a group of odd numbers? Is 2 the only, even prime number? Why?
MarkFL said:A prime number is a natural number greater than 1 that only has 1 and itself as factors. Since 2 is greater than 1 and only has 1 and 2 as factors, it is therefore a prime number. It is the only even prime number because all other even numbers also have 2 as a factor. :)
