1. Problem: If ‘p’ and ‘q’ are natural numbers and ‘p’ is a multiple of ‘q’, find the HCF of ‘p’ and ‘q’.
2. Since p is a multiple of q, we can write $p = kq$ for some natural number $k$.
3. The Highest Common Factor (HCF) of two numbers where one is a multiple of the other is the smaller number.
4. Therefore, the HCF of $p$ and $q$ is $q$.
Final answer: (c) q
Hcf Multiple Ad3271
