If they have no prime factors in common, their GCF is 1.
By finding their common prime numbers.
If you take all the common prime factors between numbers and multiply them it will give you the gcf.
You need at least two numbers to find a GCF.
7 and 17 are both primes numbers. The means that to find the LCM we need multiply them. The LCM of 7 and 17 is 7x17 which is 119. If two numbers are prime, then they are also relatively prime and in general the way to find the LCM of relatively prime number is to multiply them together.
You need at least two numbers to find an LCM. It doesn't matter whether they are prime or composite.
If you are looking for two prime numbers whose difference is 1, then the numbers have to be 1 & 3.

Prime numbers are used to find the LCM of numbers Prime numbers are used to find the HCF of numbers Prime numbers are used to simplify fractions Prime numbers are used to find the LCD of fractions
Prime numbers are used to find the product of the prime factors of composite numbers.
There is no need to do prime factorization as prime numbers are already prime. You do not need to find the prime numbers that when multiplied together create the number.
prime numbers, co-prime numbers
Prime numbers have only two factors.
Nobody. That is because there is no pattern to prime numbers. There are various methods to find some classes of prime numbers but none that will find all of them.
Two numbers are relatively prime if their GCF is 1.
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.)
You find the first 20 prime numbers and add them together. There is no formula for generating a sequence of prime numbers and so none for the series of their sums.You find the first 20 prime numbers and add them together.

No. You can only find the LCM of at least two numbers, prime or otherwise. The LCM of any two prime numbers is their product.
