41 43 and 47
39 and 48 are not prime numbers
23 29 31 37.
Yes, it is. It is greater than some numbers and less than others.
These numbers are called prime. There are many,many prime numbers, some of which are 13,23, and 7
The sequence of prime numbers starts with 2, 3, 5, 7, 11, 13, 17, 23, 29, 31, ...
The set of composite numbers includes all whole numbers greater than 1 that are not prime numbers. The first few composite numbers are 2, 4, 6, 8, 11, 13, etc.
Some think it is an interesting challenge. Prime numbers of up to a few hundred digits have real practical applications, in cryptography. However, the largest prime numbers found are much, much greater than that.Some think it is an interesting challenge.

Here are some examples. EX:2,3,7,11,13,19 Prime numbers are numbers that are only divided by themselves and one. So any number that can only be divided by 2 other numbers or less is a prime number!
Some of the prime numbers are 2,5,7,3,11,13,19,23....etc.

Assuming you mean positive whole numbers, then all numbers greater than 1 can be factorised using prime numbers only. Some of the numbers are prime themselves, eg 2, 3, 5, 7 and so factorise into themselves; others are composite and so factorise into the product of 2 primes, eg 8 = 2 x 2 x 2, 12 = 2 x 2 x 3
There is no formula that will generate all the prime numbers less than or equal to 500. Perhaps the "next best thing" is that there are some formulas that will generate prime numbers for certain values that are plugged in to the formula, but not necessarily all the prime numbers. For example, the formula n2 - n + 41 will generate prime numbers for all values of n from 0 to 40, but not for all values greater than or equal to 41. But even for values of n that are less than or equal to 40, while the formula will result in a prime number, it doesn't generate all the prime numbers. The first few prime numbers generated by this formula (for n = 0, 1, 2, 3, 4, and 5) are 41, 41, 43, 47, 53, and 61. But many prime numbers get "skipped over" by using this, or any other, formula.
