When looking for common factors, which approach would give the largest factor?

Finding the largest common factor of two or more numbers involves listing all the factors of each number and then identifying the highest number that appears in those lists. By listing out all the factors for each number, you can clearly see which numbers are shared among them and ultimately determine the maximum value.

This method is thorough because it allows you to visualize all possible factors and see precisely where the overlaps are. Once all factors are listed, simply selecting the greatest value from the common factors provides the largest shared factor.

In contrast, other methods such as listing all multiples or finding the smallest common multiple focus on different aspects that do not necessarily yield the largest common factor. Inspecting prime factors can help determine factors, but it may not directly provide the largest common factor without additional steps. Therefore, listing all factors and identifying the maximum is the most effective and clear approach for achieving the correct result.
