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.

Divide the top and bottom by their highest common factor (HCF).If you don't know their HCF, or are unsure of dividing by large numbers, divide top and bottom by any common factor and repeat until they have no common factor.That's how to simplify 8/28, this is it being done:8 and 28 have the HCF of 4, therefore:8/28 = (8÷4)/(28÷4)= 2/7
The GCF is 28.
The Highest Common Factor (HCF) of 64 and 56 is 8. To find the HCF, you can determine the factors of both numbers: 64 (1, 2, 4, 8, 16, 32, 64) and 56 (1, 2, 4, 7, 8, 14, 28, 56). The largest number that appears in both lists is 8, making it the HCF of 64 and 56.
4 and 336, respectively.
HCF(308, 420) = 28.
If you mean 28, 49 and 84 then the hcf is 7
HCF(8, 6) = 2.
