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
The number 10 is not prime. A prime number is divisble by itself and one, only. 10 is divisible by 1, by 2, and by 5. Thus, 10 is not a prime number.
no
No multiples of 10 are prime.
5 is the prime number.
The prime number less than 10 that, when added to either 10 or 20, results in a prime number is 3. When you add 10 to 3, you get 13, which is a prime number. Similarly, when you add 20 to 3, you get 23, which is also a prime number.
3 is a prime number but 10 and 4 isn't
