8/12 = 2/3 by dividing the numerator and denominator by their HCF which is 4
The HCF of 40 & 12 is... 4
The number is 4
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.
The HCF is 4. 16/4 is 4, 12/4 is 3
The greatest common factor is the highest number that divides exactly into two or more numbers. 8: 1, 2, 4, 8 12: 1, 2, 3, 4, 6, 12 The GCF for 8 and 12 is 4.
The GCF is 8.
HCF(8, 12) = 4.Therefore the simplest form of 8/12 is 2/3.
