Question

Definition The HCF (greatest common divisor) of two or more positive integers is the largest positive integer that divides all of them exactly. Note: Two whole numbers are co-prime if their HCF is $1$. For example, $8$ and $9$ are co-prime. Methods to Find HCF For example: Find the highest common factor of $1071$ and $462$. By prime factorisation By repeated division (long division) By Euclidean Algorithm
