Answer
Two numbers are co-primes if they have share only one as a factor.
Step-by-step explanation:
For example- 3 and 5 are co primes. Because there is no other number other than 1 which is divisible by both.
4 and 6 are not co-primes because they share two factors, that is 1 and 2. 4 is divisible by 2 as well as six.
All co-primes are not necessarily primes because an example is 4 and 9-
Prime numbers are numbers that have no other factors other than 1 and the number itself
But 4 has 3 factors that is 1, 2, and 4.
9 too has 3 factors that is 1,3 and 9
But 4 and 9 together are co-primes because they share only one factor that is one.

Answer:
two integers a and b are said to be relatively prime, mutually prime, or coprime (also written co-prime) if the only positive integer (factor) that divides both of them is 1. ... This is equivalent to their greatest common divisor (gcd) being
Step-by-step explanation:
and 3 are two prime numbers. Factors of 2 are 1, 2, and factors of 3 are 1, 3. The only common factor is 1 and hence is co-prime. Any two successive numbers/ integers are always co-prime: Take any consecutive numbers such as 2, 3, or 3, 4 or 5, 6, and so on; they have 1 as their HCF.
