39 is not a prime number because it has four factors: 1,3,13,39 and because prime number are numbers who has 2 factors.
no, 5 isnt divisable by 19. 19 is a prime number and isnt divisable by anything.
a prime number is a number that can only be divided by 1and its self... 1 isnt a prime number but 2, 3, 5, 7, 9, 11 etc... are prime numbers.
23, 37, 79 and 51 (assuming 1851 is a typo, 18 isnt a prime) if not a typo 1851 isnt a prime number anyway, it divides by 3
