810/30=27
No.
Well.... it actually depends. like 100 divided by 20 is 5 which is a prime. but 200 divided by 50 is four which is four and not a prime number.
no one will ever know ):<
No. The sum of two odd numbers is always even, and no prime is even (apart from 2, but it is the lowest prime, so no primes can be added to form it).
NO!!! By the fact that you are multiplying two numbers together, the answerv is ALWAYS composite.
Always.
Yes. For example, 52 ÷ 4 = 13.

No.
2 multiplied by itself 57,885,161 times, less one.
Nothing can be multiplied to get that number. Ex. 7 is a prime number because nothing x nothing will ever equal 7.
A prime number has exactly two factors, 1 and the number itself. 1 is not a prime number, and the product will be a composite number if any other prime is used as a factor and multiplied by another prime.

No. If you multiply two prime numbers, any prime numbers, the result will - by definition - not be a prime number. For example, if you multiply 2 x 3, the result will obviously be divisible by 2 and by 3, and therefore, not be a prime number. By the way, one is not usually considered a prime number.
No.
