Now that we've got a solid grasp on what factors are, let's move on to finding the factors of 24 and 28 and then pinpointing the ones they have in common. Get ready to become a factor-finding pro!

Finding Factors of 24

Let's start by identifying all the factors of 24. To do this, we need to find every number that divides evenly into 24. We can start with the smallest positive integer, which is 1, and work our way up. So, the common factors of 24 and 28 depend on the individual factors each number has.

  • 1 is a factor of 24 because 24 ÷ 1 = 24
  • 2 is a factor of 24 because 24 ÷ 2 = 12
  • 3 is a factor of 24 because 24 ÷ 3 = 8
  • 4 is a factor of 24 because 24 ÷ 4 = 6
  • 6 is a factor of 24 because 24 ÷ 6 = 4
  • 8 is a factor of 24 because 24 ÷ 8 = 3
  • 12 is a factor of 24 because 24 ÷ 12 = 2
  • 24 is a factor of 24 because 24 ÷ 24 = 1

So, the factors of 24 are: 1, 2, 3, 4, 6, 8, 12, and 24. Make sure to list them out in order; it'll make it easier to compare them with the factors of 28 later on. This methodical approach ensures that you don't miss any factors. Remember, factors always come in pairs, which is why we stopped checking after we reached 6 (since 4 x 6 = 24). Knowing this trick can save you time and effort!

Understanding the factors of 24 is essential not just for this exercise, but also for understanding its composition. Think of factors as the building blocks of a number. Knowing these building blocks helps in many areas of mathematics, from simplifying fractions to understanding prime factorization.

Identifying Factors of 28

Now that we've nailed the factors of 24, let's move on to finding the factors of 28. Just like before, we need to identify all the numbers that divide evenly into 28. This will involve the same systematic approach to ensure we don't miss any crucial numbers. The common factors of 24 and 28 are determined by comparing these individual factor lists.

  • 1 is a factor of 28 because 28 ÷ 1 = 28
  • 2 is a factor of 28 because 28 ÷ 2 = 14
  • 4 is a factor of 28 because 28 ÷ 4 = 7
  • 7 is a factor of 28 because 28 ÷ 7 = 4
  • 14 is a factor of 28 because 28 ÷ 14 = 2
  • 28 is a factor of 28 because 28 ÷ 28 = 1

So, the factors of 28 are: 1, 2, 4, 7, 14, and 28. Notice how each factor has a corresponding pair? This helps to confirm that we've found all the factors. Listing these factors out clearly is super important for the next step, where we'll compare them with the factors of 24 to find the common ones. Understanding the factors of 28 is just as crucial as understanding those of 24 because these are the numbers we'll use to determine our common ground.

Understanding the factors of 28 also provides insights into the number's properties. For instance, we can see that 28 is a composite number, meaning it has more than two factors (1 and itself). This is different from prime numbers, which only have two factors. Recognizing such properties can be useful in various mathematical contexts. So, with the factors of both 24 and 28 now identified, we're perfectly positioned to find those shared factors. Let's get to it!

One common example is in cooking. Let's say you're baking a cake and the recipe calls for 24 chocolate chips and 28 nuts. You want to divide the cake into equal slices, each with the same number of chocolate chips and nuts. To do this, you need to find the common factors of 24 and 28. As we discovered earlier, the common factors are 1, 2, and 4. This means you can divide the cake into 1, 2, or 4 slices, each containing an equal number of chocolate chips and nuts.

Another real-world application is in scheduling. Imagine you're organizing a team-building event and you have 24 employees in the marketing department and 28 employees in the sales department. You want to divide them into smaller groups for different activities, ensuring that each group has an equal number of employees from both departments. Again, you need to find the common factors of 24 and 28. Using the common factor of 4, you can create 4 groups, each with 6 employees from marketing and 7 employees from sales. This ensures a balanced and fair distribution of employees across all activities.

Moreover, common factors are used extensively in business and finance for inventory management, resource allocation, and financial planning. For instance, a store manager might use common factors to determine how to divide shelf space among different product categories, ensuring a balanced and efficient use of available space. Similarly, a financial analyst might use common factors to simplify complex financial ratios and make informed investment decisions. These real-world applications demonstrate that understanding common factors is not just an academic exercise but a practical skill that can be applied to solve everyday problems in various fields.
