Final Answer:

The GCD and LCM of the given pair of natural numbers, 66 and 88, is 22 and 264, respectively.

Step-by-step explanation:

To find the Greatest Common Divisor (GCD) and the Least Common Multiple (LCM) of two numbers, 66 and 88, we can follow these steps:

**Greatest Common Divisor (GCD):**
1. List the factors of each number.
2. Identify the highest factor that appears in both lists.

Let's find the factors:

For 66:
1, 2, 3, 6, 11, 22, 33, 66

For 88:
1, 2, 4, 8, 11, 22, 44, 88

The common factors of 66 and 88 are:
1, 2, 11, and 22

Out of these, the highest common factor is 22, which means the GCD of 66 and 88 is 22.

**Least Common Multiple (LCM):**
The LCM of two numbers is the smallest multiple that is exactly divisible by both numbers.

There's a relationship between the LCM and GCD of two numbers, which is given by the formula:

LCM (a, b) = (a*b) / GCD

Using this formula and the GCD we found, we can calculate the LCM.

For 66 and 88:

LCM (66, 88) = 66*88 / 22

First, calculate the product of the two numbers:

66*88 = 5808

Next, divide by the GCD we found, which is 22:

5808/22 = 264

So the LCM of 66 and 88 is 264.

In summary, the GCD of 66 and 88 is 22, and the LCM is 264.
