Answer 1

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 2

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.
