How many prime numbers are divisible by 210?
None, if a number is divisible by 210 then it is not a prime number!
How many prime numbers divisible by three?
No prime numbers are divisible by 3. By definition a prime number isn't divisible by anything but itself and 1.
How many prime numbers are divisible by 11?
Just the one: 11 itself. If any other number were divisible by 11 that number would not be a prime.
How many prime no is divisible only by it self and 1 but not by any other number?
All prime numbers are divisible only by one and themselves.
How many prime numbers are there between 20 and 200 end with an 8?
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".

Why are not all odd numbers greater than 3 are prime numbers?
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.
How many prime numbers are divisible by 12?
None. 12 is a composite and any number divisible by a composite is itself a composite.
What number is greater than 1 and divisible only by itself and 1?
These numbers are called prime. There are many,many prime numbers, some of which are 13,23, and 7
Are there more prime numbers that are odd or even?
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.
What are all the prime numbers with 1 in the units place?
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 ...
How Many Prime Numbers are Odd?
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.
Is there more prime numbers then composite numbers?
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.
