Questions & Step-by-Step Solutions
If the HCF of two numbers is 1, what can be said about the numbers?
Correct Answer: The numbers are coprime.
Step 1: Understand what HCF means. HCF stands for Highest Common Factor, which is the largest number that divides two numbers without leaving a remainder.
Step 2: If the HCF of two numbers is 1, it means that the only number that can divide both of them is 1.
Step 3: When two numbers have no common factors other than 1, we say they are coprime.
Step 4: Therefore, if the HCF is 1, we can conclude that the two numbers are coprime.
Coprime Numbers – Two numbers are coprime if their highest common factor (HCF) is 1, indicating they share no common divisors other than 1.
