yes, also as other's mentioned, it is the only Prime Number that is even. By the way, Prime Numbers other than 2 (1 is not Prime, it is the mult identity) always end in either 1, 3, 7 or 9. Yet, if a Number ends in 1, 3 , 7 or 9, it doesn't mean that it is a Prime Number only a possible candiadte for being Prime. Some Primes are:
2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31,.... If a Number ends in 0 or 5 or 2 (except for the Prime Number of 2), it is NOT Prime.
Is 377 Prime? I say yes. You need to try to divide it by different primes until you realize it is either prime or not. For large numbers you need a Computer program.
Is 297 prime? No. 297=3*99
Is 89 prime? yes.

Two is a prime number because it only divides into the number 1 and itself (2). It also happens to be the only even prime number.

Yes. The only reason all other even numbers aren't primes is because 2 is a prime number. If you argue that 2 isn't a prime because it's even, then 3 can't be a prime becasue it is a multiple of three, and all multiples are not prime numbers.

Yes. A prime number is defined as a number which is divisible by only that number and 1 (or whose multiples are that number and 1). It is therefore the only even prime number, since any other even number would also be divisible by 2.

yes. the only numbers that can divide into 2 are 1 and 2, the definition of prime numbers. a prime number is a number that can be divided only by 1 and itself. it is also the only prime number that is even.

Yes. As it has only two factors 1 and 2 (itself) so it is a prime number. Infact its the only even prime number.

Yes. If you factor two, there are no other whole, positive factors other than 1 and 2. If the only positive whole factors of a number are the number and 1, then the number is prime.

2 is a prime number as it is only divisible by only 2 numbers, 1 and 2.
