Prime numbers are positive integers which can be evenly divided only by 1 and themselves. There is no other rule for all prime numbers.
2, 3, 5, and 7.Prime numbers obey the simple rule: Prime numbers can only be divided by 1 and themselves. Which means that they only have two factors.1 is also sometimes considered a prime number, but it is not. It has only one factor, so disobeys the rule.
Any two prime numbers will be relatively prime. Numbers are relatively prime if they do not have any prime factors in common. Prime numbers have only themselves as prime factors, so all prime numbers are relatively prime to the others.
There is no simple answer because there is no simple rule for primes: it is certainly NOT an arithmetic progression.
The opposite of prime numbers are composite numbers.
It can only be divided by 1 and 7.

That will be difficult to answer specifically without the list of numbers, but as a general rule, test up to the square root.
Those are the first four prime numbers.

Multiply them together.
Some are. As a general rule, prime numbers are better.
There are infinitely many prime numbers so it is impossible to memorise them. Prime numbers do not follow any simple rule so it is not possible to memorise them by learning a rule either. Your best bet is to use them often so that you become familiar with them and so will recognise them. Also, learn the factorisation of odd numbers - since after 2, you need not bother with even numbers.
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.
It is not a rule as such; those number are the first 10 prime numbers.
