The HCF is 4
The highest common factor of 4, 6 and 8 is 2.
To find the HCF of two numbers, you need to express them in their prime factors: 8 = 2x2x2 28 = 2x2x7 The next step is to identify any common prime factors. In this case both numbers have two 2s as prime factors. Multiply these together and you get: 2x2 = 4 Thus 4 is the hcf of 8 and 28.
