Any number which is only divisible by either itself or 1, is a prime number.
In the list oyu have given, 7, 13 and 19 are not divisible by any other number except itself or 1. Hence these are prime numbers.

prime numbers are numbers that are divisible by the number itself and 1...
i think to find prime numbers you try to divide the number by 2,3,5,7 respectively.....if you don get a whole number then it's probably a prime number....
the prime numbers are 7,13 and 19
