The GCF is 2.
the hcf of 12 and 20 = 4
It is 1 but the HCF is 2
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.
If you mean 28, 49 and 84 then the hcf is 7
It is: 4
The GCF is 2.
Since 12 is a factor of 24, it is automatically the GCF.
The GCF is 4.

the hcf of 12 and 20 = 4
If you mean 12, 16 and 28 then the HCF is 4
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
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.
