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.

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. 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".

All prime numbers are divisible only by one and themselves.

None. 12 is a composite and any number divisible by a composite is itself a composite.

These numbers are called prime. There are many,many prime numbers, some of which are 13,23, and 7

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.

prime numbers between 0 -100 which are divisible by 7: 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.
