Take each number in turn, call it "n", and check whether it has any factors f, such that 1 < f < n. If it doesn't, it is a prime number.

There is no simple answer because there is no known pattern for prime numbers. So the answer is to find all the primes below 70 and add them together. Sorry, but no short cut for this.
Prime factorization and the Euclidean algorithm
You just have to work out it,take each number below it and check whether it is prime or not.
You seek for prime numbers that are approximately 200 digits big, then multiply them. I don't know details about the algorithms, but I understand that for cryptography, instead of using an algorithm that will be guaranteed to give a prime number, an algorithm is used, instead, that has a very, very high probability of giving a prime number. Probably this is done because it is faster.
Just go to a table of prime numbers, find the prime numbers, and add them.Just go to a table of prime numbers, find the prime numbers, and add them.Just go to a table of prime numbers, find the prime numbers, and add them.Just go to a table of prime numbers, find the prime numbers, and add them.
If you use methods based on prime factors, it is the same whether you have 2, 3, or more numbers: find all the factors that occur in any of your numbers. If you use a method based on Euclid's Algorithm (that is, lcm(a, b) = a x b / gcf(a, b), where you find the gcf with Euclid's Algorithm), then you can find the lcm for two numbers at a time. For example, to get the lcm of four numbers, find the lcm of the first two, then the lcm of the result and the third number, than the lcm of the result and the fourth number.

Prime numbers are used to find the product of the prime factors of composite numbers.
No, there is no single definitative equaltion that will predict all prime numbers between 1 and 1000, while not including some composite numbers. However, there are many "rules of thumb" that can greatly increase the efficiency of an algorithm to find the primes. For example, all prime numbers greater than 6 are either one more or one less than a multiple of six. This combined with the 11 primes less than the square root of 1000, makes the algorithm 8 times as effective as a brute force approach.
