They are both prime.
They are coprime.

Q: If the HCF of two numbers is 1, what can be inferred about the two numbers? (2023)
Solution: If the HCF is 1, it means the two numbers are coprime, meaning they have no common factors other than 1.
Steps: 4
Step 1: Understand what HCF means. HCF stands for Highest Common Factor, which is the largest number that divides two or more numbers without leaving a remainder.
Step 2: Recognize that if the HCF of two numbers is 1, it means that the only number that can divide both of them is 1.
Step 3: Realize that having no common factors other than 1 means that the two numbers do not share any other divisors.
Step 4: Conclude that if two numbers have an HCF of 1, they are called coprime or relatively prime.
