The prime numbers up to 30 are 2, 3, 5, 7, 11, 13, 17, 19, 23, and 29.

Prime numbers cannot be made up from multiplying other numbers. Primary colours cannot be made up from adding other colours.
There is an infinite number of prime numbers after 500!
The prime numbers up to 50 are: 2,3,5,7,11,13,17,23,29,31,37,41,43,47.
Prime numbers are those numbers which are only divisible by itself Likewise, 1,3,5,7,11,13,17,19,23,,29,31,37,41,43,47,51,53,57,59. These are the only prime numbers upto 60.
For this kind of question, I would suggest looking up a table of prime numbers. As an alternative, you can try to find factors for each of the numbers - if it has a factor, it is NOT a prime. For this range of numbers, testing for prime numbers up to 13 is appropriate. (If 17 is a factor of one of these numbers, the other factor is less than 17, so you would already have found it before you reach 17.)
So the composite numbers won't get all bunched up.
2,3,5,7,11,13,17,19,23,29,31,37,39,41,43,47,51,53,57,59,61,67,71,73
There are no prime numbers greater than 10 that add up to 29. Since all prime numbers greater than 2 are odd numbers, no two prime numbers greater than 2 can have an even number for their sum.
The LCM of {9,5,4,10} is 180.The prime factorization of these numbers are:9=3*35=2*54=2*210=2*5By finding the common factors of all of the numbers, you end up with 2*2*3*3*5, which is 180.
Look up a table of prime numbers. All those numbers that are not prime, are composite - except 1, which is neither prime nor composite.
The quoted numbers are all PRIME Numbers. The next prime numbers after '11' are , 13 ,17,19,23,29,31,37,41,43,47, up to '50' Prime Numbers , like ordinary numbers, go to infinity. NB After '2' , there are no. even prime numbers. They are all ODD NUmbers.
The prime numbers up to 30 are 2, 3, 5, 7, 11, 13, 17, 19, 23, and 29.
All of them. Any number greater than one can be relatively prime.
