List the prime numbers from 2,4,5,7,12,15,16,17,19,20,21,23,27,29,30

The NEWYES NY-991MS and CTIFREE fx-991ES PLUS calculators do not have a dedicated "FACT" button like the Casio FX-83GTX. However, you can still find prime numbers on these calculators.
To find prime numbers:
NEWYES NY-991MS:
Press the "MODE" button.
Choose "PRIME" from the list of options.
Enter the desired number and press "=" to check if it's prime.
CTIFREE fx-991ES PLUS:
Press the "MODE" button.
Select "TABLE" or "TABLESET."
Input a starting point and an ending point, then observe the table for prime numbers.
Although the techniques may vary from those used on the Casio FX-83GTX, they prove to be effective for prime number calculations on the designated calculators.

Amazon has a contact us page that has details on how to reach them for Prime issues. The link for the Contact Us page is here:

There is an option where you can enter your phone number and have them call you. You can also call the general help number to have Prime questions answered. 1-888-280-4331

Presume you know that prime number is divisible only by itself. See here:

There are an infinite number of prime numbers so a complete list is impossible. You can see the first 500 prime numbers at http://en.wikipedia.org/wiki/List_of_prime_numbers#The_first_500_prime_numbers

It is any number only divisible by itself and 1 (giving whole number results). A list here of the first 1000

There are an infinite number of prime numbers, so I can't list them all. For the first 500 prime numbers, see http://en.wikipedia.org/wiki/List_of_prime_numbers#The_first_500_prime_numbers

A prime number is a positive whole number (natural number) which cannot be divided into smaller whole numbers. In short, it can only be divided (integer division) by itself and 1.
First prime number is 2, then 3, 5, 7, 11, 13, 17, 19,
To generate a list of prime numbers the Greek Eratoshenes used a method called now the sieve Eratosthenes.

1. Write all the natural numbers up to some chosen limit (100, 259, any limit )
2. Remove 1 by crossing it ( 1 is no longer considered prime).
3. The first prime number is 2. Circle the number 2.
4. Go through the whole list crossing out all the numbers that are multiple of 2, that is 4, 6, 8,10,12, ...
5. Repeat.
6. The next prime number is 3 since it was not crossed out as a multiple of 2. Circle 3.
7. Go through the whole list crossing all the numbers that are multiples of 3, and which have not already been crossed out as multiples of 2 .
8. Number 4 has been crossed out already.
9. Next prime number is 5. Circle 5
10. Go through the whole list crossing all the numbers that are multiple of 5 and which have not been crossed out already as multiples of 2, or 3
11. Repeat:
12. Next prime number is 7. Circle 7
13. Go through the whole list again, crossing out the multiples of 7, and so on.

If you want to test the primality of a positive integer (odd number) starting by dividing it by 3 (use divisibility rules or otherwise), then divide by 5, by seven, and all subsequent prime numbers. If it is not divisible by any prime number, keep going but do not exceed the prime number that is closest yet smaller than square root of your number.

Enjoy.

Are you serious?

The only prime number in the list is 37.

"A prime number (or a prime) is a natural number greater than 1 that has no positive divisors other than 1 and itself." - wikipedia
A list would be impossible without a limit. if you can't divide it by anything but 1 and the number itself(which would also mean that you were dividing by one), then it's prime.
4 is not prime, because it is divisible by 1, 2, and 4. 5 is prime, because it cannot be divided by anything except 1 and 5(itself).
