To find the HCF of 8 and 12, first write them as the product of their prime factors:
8 = 2x2x2
12 = 2x2x3
The next step is to identify any common prime factors. In this example, both numbers have two 2s as prime factors. Multiply these together and you get 4. Thus the HCF of 8 and 12 is 4.
8
4
The GCF is 8.
The GCF is 2.
Since 12 is a factor of 24, it is automatically the GCF.
4
12
4
It is: 4
the hcf of 12 and 20 = 4
It is 1 but the HCF is 2
The GCF is 2.
8/12 = 2/3 by dividing the numerator and denominator by their HCF which is 4
HCF(8, 12) = 4.Therefore the simplest form of 8/12 is 2/3.
