If you are looking for two prime numbers whose difference is 1, then the numbers have to be 1 & 3.
5 and 3 are two numbers less than 7, whose difference is 2.
Twin primes
17 and 53
Eight
The answer is 47-13=34
two prime numbers whose product is 141 = 3 & 47
7and 5(7-5=2)
They are known as twin primes. 3 and 5 5 and 7
None of this works. There aren't two prime numbers that multiply to 75 and the only two that add to it are 73 and 2. There aren't two prime numbers whose difference is 19. Two numbers that satisfy those conditions are 47 and 28, but 28 isn't prime.
Two numbers whose GCF is one are relatively prime or co-prime
17 and 3 are two prime numbers whose sum is 20. Their product is 51.
