Questions & Step-by-Step Solutions

If the HCF of two numbers is 1, what can be said about the two numbers? (2023)
  • 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: Since the only common factor is 1, it means that the two numbers do not share any other factors.
  • Step 4: When two numbers have no common factors other than 1, we say they 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.
