Answer 1

Answer:

The HCF (Highest Common Factor) of two or more numbers is the highest number among all the common factors of the given numbers or in simple words, the HCF (Highest Common Factor) of two natural numbers x and y is the largest possible number that divides both x and y. Let's understand this definition using two numbers, 18 and 27. The common factors of 18 and 27 are 1, 3, and 9. Among these numbers, 9 is the highest (largest) number. So, the HCF of 18 and 27 is 9. This is written as: HCF (18,27) = 9
