There is only one Prime number divisible by 3 and it is 3 itself which is a prime number.

No prime numbers are only divisible by one and by themselves.


Prime numbers are only divisible by 1 and themselves. So, a prime number cannot be divisible by 10. The only prime number that is divisible by 2 is 2 itself; all other numbers divisible by 2 are not prime numbers.


In contrast, no prime numbers are divisible by 10. Any prime number is divisible only by itself and 1.


A set of even numbers cannot be relatively prime. They are all divisible by 2.


A set of even numbers cannot be relatively prime. They are all divisible by 2.


45 is not prime so it is composye!


A prime number isn't divisible by anything by itself and 1. All even numbers are divisible by 2. Therefore, all prime numbers are odd.


All prime numbers are divisible by 1. There are an infinite amount of them, so it is impossible to list them.


2 is the only member of both the set of all prime numbers and the set of all even numbers.


All non-zero integers are divisible.


no, because then they would be divisible by the number you multiplied it by.


No, prime numbers are the numbers that can be divisible by itself. The only even prime number is 2.


A prime, or prime number, is a number greater than 1, whose only factors are 1 and itself.For example, the first few prime numbers are 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, ... (note: the set of prime numbers is infinite).As you can see, all prime numbers except 2 are odd. Further examples:9 is not a prime number, since it is divisible by 3.15 is not a prime number, it is divisible by 3.25 is not a prime number, since it is divisible by 5.A prime, or prime number, is a number greater than 1, whose only factors are 1 and itself.For example, the first few prime numbers are 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, ...

All numbers are divisible by 1. So, apart from the number 1, all numbers are divisible by another number. These numbers are therefore prime or composite.


The set of even numbers is the set of all the numbers that are divisible by 2 (or multiples of 2).


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.



No. For example, 9 wouldn't be prime because it is divisible by 3.


Prime numbers are whole numbers that are not divisible by anything but one and itself. Examples of prime numbers include 1;2;3;5;7;9... etc. Prime numbers must always be odd (except for 2) but not all odd numbers are prime. For example, 21 is odd, but it is divisible by 3 and 7. Therefore, it is not prime.


All prime numbers are odd numbers. If one were even, it would be divisible by two and would, therefore, not be prime.


291 is not prime. It is at least divisible by 3 and 97. This makes it not prime since all prime numbers must only be divisible by 1 and itself.


Prime numbers are integers that are not divisible by anything except one and themselves. All prime numbers (excepting two) are odd.


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 ...


They are all divisible by 1 because they are all prime numbers.
