To find the other number, you can use the relationship between HCF, LCM, and the product of two numbers.

- Product of the numbers = HCF × LCM

- In this case, that equals 126 × 9 = 1134.

- If one number is 18, the other number can be found by dividing: 1134 ÷ 18.

- Perform the division: 1134 ÷ 18 = 63.

Here's a look at the options provided:

- Option 1: 63 - This matches our calculation.

- Option 2: 36 - Doesn't fit the calculated product.

- Option 3: 84 - Exceeds our calculated product of the other number.

- Option 4: 24 - Smaller than the calculated product of the other number.

Therefore, the correct answer is Option 1: 63.
