Detailed Solution

Concept- The HCF of two co-prime numbers is 1.
The term "HCF" stands for the greatest number that can divide the two numbers whose factors we are examining. Think about the solution using the idea that two integers are said to be coprime if the only positive integer that can divide both of them is 1.
In number theory, p and q are said to be coprime, mutually prime, or relatively prime if there is only one positive integer that divides them both. Any prime number that divides one does not divide the other, for that reason. This translates to having a greatest common divisor of 1 for them.
For instance, the prime factors of the integers 2 and 3 are either 1 or the number itself.
Since both prime numbers may be split by one, they are referred to as co-prime numbers.
And one is the biggest common divisor.
A pair of co-prime numbers H.C.F. is therefore 1.
Hence, the correct answer is option 1.
