Answer:
There should be a minimum of two numbers to form a set of coprime numbers. Such numbers have only 1 as their highest common factor, for example, {4 and 7}, {5, 7, 9} are coprime numbers. Co-prime numbers need not be prime numbers always.

Answer:
False
Step-by-step explanation:
Co Prime Numbers: Two numbers are said to be co-prime numbers only if their common divisor is 1 or highest common factor(HCF) is 1.
Prime Numbers : Prime number is a natural number which is only divisible by itself and it cannot be made by multiplying any other numbers.
If two numbers are co-prime that is not necessary that one of them must be a prime number. For example 8 and 9 are co-prime numbers but none of them are prime numbers.
