Answer 2

Answer: 1

Explanation: The factors of p & q are 1 and the number themselves (property of prime number). So, highest common factor = 1.

Similarly, two consecutive natural numbers also have the HCF = 1.

More:

• HCF(p, q) = Product of common power of each common factor of the numbers.
• LCM(p, q) = Product of greatest of power of involved numbers.
• LCM(p, q) × HCF(p, q) = p·q
• LCM(p, q, r) = $\rm \dfrac{p \cdot q \cdot r \cdot HCF(p, q, r)}{HCF(p, q) \cdot HCF(q, r) \cdot HCF(p, r)}$
• HCF(p, q, r) = $\rm \dfrac{p \cdot q \cdot r \cdot LCM(p, q, r)}{LCM(p, q) \cdot LCM(q, r) \cdot LCM(p, r)}$
• HCF of fractions = (HCF of num.)/(LCM of den.)
• LCM of fractions = (LCM of num.)/(HCF of den.)
