None, if a number is divisible by 210 then it is not a prime number!
No prime numbers are divisible by 3. By definition a prime number isn't divisible by anything but itself and 1.
Just the one: 11 itself. If any other number were divisible by 11 that number would not be a prime.
All prime numbers are divisible only by one and themselves.
None. A number that ends with 8 is even, that is, divisible by 2. ================================ To be prime a number must only be divisible by itself and 1 thus any number divisible by 2 can not be a prime number. Therefore the answer to your question is:- "There are no prime numbers between 20 and 200 that end with an 8".

Because many of them are divisible by smaller odd numbers. For example 35 is divisible by 5 and so 35 cannot be a prime number.
None. 12 is a composite and any number divisible by a composite is itself a composite.
There are infinitely many prime numbers. There is only one even prime number, which is 2, because all other even numbers are divisible by 2 and thus are not prime. So, there are infinitely many odd prime numbers and only one even prime number.
These numbers are called prime. There are many,many prime numbers, some of which are 13,23, and 7
All of them??? There are probably infinitely many. Here are the first few numbers with 1 in the units place: 1: Not usually considered a prime number. 11: Prime 21: Not prime (divisible by 3) 31: Prime 41: Prime 51: Divisible by 3 61: Prime 71: Prime 81: Divisible by 3 91: Divisible by 7 101: Prime ...
Infinite. All prime numbers are odd with the exception of 2. Prime numbers are only divisible by 1 and themselves. That's the rule. The only prime number that is even is 2 since all other even numbers are divisible by 2 also. Hence all prime numbers are odd with the exception of 2.
There are many, many more composite numbers than prime numbers. For example, beyond the number 3, every other number is composite, as it is divisible by 2. Following this, every number ending with a 5 other than 5 itself is composite, as it is divisible by 5, and every third odd number is divisble by 3. There are many complicated divisibility tests for numbers above 5.
