4

The highest common factor (HCF) of two numbers is the largest factor that both numbers share. To determine the HCF of 12 and 16, we start by identifying the factors of each number.

For 12, the factors are: 1, 2, 3, 4, 6, 12.

For 16, the factors are: 1, 2, 4, 8, 16.

Next, we look for the common factors between these two sets. The common factors of 12 and 16 are 1, 2, and 4. Among these, the largest one is 4. Therefore, the HCF of 12 and 16 is correctly identified as 4.

Finding the highest common factor is an important skill in mathematics, as it can be used in various applications such as simplifying fractions, finding equivalent ratios, and solving problems involving divisibility. In this case, the correct answer helps in understanding the concept of divisors and how to identify them for two given numbers.
