What is the highest common factor of 24 and 28?

Answer 1

To find the highest common factor of two numbers you first need to break them down into their prime factors. In this case:

24 = 2x2x2x3

28 = 2x2x7

The next step is to identify the common factors. In this case, both numbers have two 2s as a factor. We multiply these together to get the HCF:

2x2=4

Thus 4 is the highest common factor of 24 and 28.

Answer 2

To find the greatest common factor of 16 and 24 you first need to split them into their prime factors:

16 = 2x2x2x2

24 = 2x2x2x3

The next step is to identify any common factors. In this case, both numbers have three 2s as prime factors. To find the GCF, you multiply these numbers together:

2x2x2 = 8

Thus the greatest common factor of 16 and 24 is 8.

Answer 3

The GCF is 8.

Answer 4

The Greatest Common Factor (GCF) is: 8

Answer 5

The GCF of 16 and 24 is 8.
