What is the HCF of 8 and 28?

Answer 1

Oh, dude, the Highest Common Factor (HCF) of 8 and 28 is like the coolest number that can divide both of them without leaving a remainder. So, for these two numbers, the HCF is 4 because 4 is the largest number that can divide both 8 and 28 evenly. Like, that's math for you, man.

Answer 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.
