Co-Prime Numbers
Co-prime numbers are the numbers which have no common factors other than 1. In other words, two numbers are said to be co-prime if their HCF (highest common factor) is 1.
Explanation
- Option 'A', 2 and 3 are co-prime numbers because they have no common factors other than 1. Therefore, the correct answer is option 'A'.
- Option 'B', 2 and 4 are not co-prime numbers because they have a common factor of 2.
- Option 'C', 2 and 6 are not co-prime numbers because they have a common factor of 2.
- Option 'D', 2 and 110 are not co-prime numbers because they have a common factor of 2.
Therefore, the only pair of co-prime numbers among the given options is 2 and 3, which is option 'A'.
