the hcf of 12 and 20 = 4
4
4
The GCF is 4.
The GCF is 2.
The GCF is 2.
20/12 = 5/3 by dividing the numerator and denominator by their HCF which is 4
HCF is the highest common factor of two or more numbers. HCF of 20 and 200 is 20.
To work this out, you need to write both numbers as their prime factors: 20 = 2x2x5 12 = 2x2x3 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 4. Therefore 4 is the HCF of 20 and 12.
The GCF is 20.
The GCF is 4.
The GCF is 1.
