1. '2' is the only prime number that is an even number. 2. A prime number can only be divisible by '2' and itself. 3. '1' is not a prime number as it can only be divided by '1', which is itself.

1. A prime number is an integer that can only be divided by 1 and itself. 2. We can use a method called 'The Sieve of Eratosthenes' to find out what integers are prime numbers and which ones are not. 3. 1 is not a prime number.

1.a prime number is a number that can only be devided by one or itself 2.0 is not a prime 3.2 is the only even prime number

and i found these somewhere : 1) Every prime above 3 is always 1 number away from a multiple of 6. 2) For primes bigger than 3 again; if you square a prime and take 1 away from this; the answer is always divisible by 24. 3) Any prime number above 2 is the difference of two squares of two other integers....(as is the case for any odd number)

4) Think of a number; double it. There's at least one prime number in between these two numbers.

1. All prime numbers are odd numbers except 2. 2. If we add two prime numbers together (except for 2), the answer will be an equal number as the sum of two odd numbers is an even number. 3. We can use methods like 'The Sieve of Eratosthenes' to aid us in finding prime numbers faster.

1. All prime numbers can only be divided by 1 and itself. 2. All prime numbers are above 1. 3. Methods such as 'The Sieve Of Eratosthenes' can be used to figure out prime numbers easier.

Only small prime numbers.

DeleteIt actually can find numbers bigger than 100 as well, just that you need much more time to find them.
