To find the greatest common factor (GCF) of 16 and 24, we can use different methods. According to, one way to find the GCF is to compare the prime factorization of each number. The prime factorization of 16 is 2 x 2 x 2 x 2, and the prime factorization of 24 is 2 x 2 x 2 x 3. When we compare the prime factorization of these two numbers, we can see that there are matching prime factors of 2 x 2 x 2. Therefore, we can find the GCF of 16 and 24 by multiplying all the matching prime factors to get a GCF of 8. This result is also confirmed by, which states that the GCF of 16 and 24 is 8. Therefore, the GCF of 16 and 24 is 8.
