Yes, 997 is a prime number.You can either work it out, or look it up in a list of prime numbers!For list of the first 1,000 prime numbers, see Related links below this box.
Please note that there are infinitely many prime numbers. An Internet search for "list of prime numbers" will quickly give you a list of prime numbers up to a certain point, for example here: http://en.wikipedia.org/wiki/List_of_prime_numbers Any integer greater than 1 that is not in the list of prime numbers is a composite number. (1 is considered neither a prime number, nor a composite number.)
The prime numbers that make up 50 are 2 and 5. 50 can be expressed as the product of 2 and 5, which are both prime numbers. Prime numbers are numbers that are greater than 1 and can only be divided by 1 and themselves without leaving a remainder.
2+7+41=50
There are 15 prime numbers up to 50.
The prime numbers up to 50 are: 2,3,5,7,11,13,17,23,29,31,37,41,43,47.
Look up a list of prime numbers (a Google search for "prime numbers" or "list of prime numbers" should do); every number (greater than 1) that is NOT a prime number is composite.
The given numbers of 15 and 35 are not prime numbers but they add up to 50

Any number greater than 1 can be co-prime.
2+7+41=50
5 is the only prime number in which 5 is a factor.
That will be difficult to answer specifically without the list of numbers, but as a general rule, test up to the square root.
