Question

Find the HCF of two co-prime numbers.

Answer 1

Find the HCF of two co-primes:

Two numbers are called co-prime when the highest common factor (HCF) of the numbers is $1$.

For example, the only common factor of $3$ and $4$ is $1$.

Hence, $3$ and $4$ are co-prime.

Therefore, the HCF of two co-prime numbers is $1$.
