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.

By four prime numbers which are: 2 3 5 and 7

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.

Prime numbers are only divisible by 1 and itself... so no prime number can be divisible by the numbers you listed.

Only one . . . the prime number '2'.

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.

Four and they are: 2, 3, 5 and 7

Only 2 itself.

There are no prime numbers anywhere that are divisible by 2 and 7.

No. The only prime number divisible by 2 is 2.

Prime numbers have the distinction that their only factors are 1 and themselves. So 2 is a prime, and it is divisible by itself, but that's the only one.
