The ancient Greeks.
It is hard to for historians to know exactly who "discovered" prime numbers. It is believed that the ancient Egyptians had some knowledge about prime numbers. However it was the ancient Greeks who get most of the credit for being the "first" to study prime numbers.
Use the prime factorizations to determine the GCF. If the GCF is 1, the numbers are relatively prime. If the two numbers have no prime factors in common, they are relatively prime.
Prime numbers only have one and themselves as factors.
If the prime factorizations have no prime factors in common, the numbers are relatively prime.
The ancient Greeks.
They were known, at least, to the Ancient Greeks - perhaps earlier. I believe it was one of the Ancient Greeks who proved that the set of prime numbers was infinite (or "larger than any given set", or that there was no last prime number).They were known, at least, to the Ancient Greeks - perhaps earlier.

The earliest records of any knowledge of prime numbers dates back to ancient Egypt. The ancient Greeks were the first people known to explicitly study prime numbers.
The earliest surviving records of the explicit study of prime numbers come from the Ancient Greeks.
In every math problem you can ever do you can use prime numbers. 1+3 Both prime numbers. Most numbers are not prime but prime numbers only become a broblem when you try to factor them like in simple algebra.

Prime numbers are prime numbers - whether we count in the decimal, binary, hexadecimal or another base.
Prime numbers only have one and themselves as factors.
The Egyptians were the first people to have some knowledge in prime numbers. Though, the earliest known record are Euclid's Elements, which contain the important theorem of prime numbers. The Ancient Greeks, including Euclid, were the first people to find prime numbers. Euclid constructed the Mersenne prime to work out the infinite number of primes.
This is not known.It is believed that the ancient Egyptians knew of them, but it is known that the ancient Greeks did.
If the prime factorizations have no prime factors in common, the numbers are relatively prime.
