Use Euclid's division algorithm to find the HCF of
(i) `135` and `225`     (ii) `196` and `38220`    (iii) `867` and `255`

Explanation

To find the HCF of the given pairs of numbers using Euclid's division algorithm, we will follow these steps:

### (i) HCF of 135 and 225

1. **Identify the numbers**: We have 135 and 225. Since 225 is greater than 135, we will divide 225 by 135.

2. **Perform the division**:
