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.
4 and 24 8 and 12
8/12 = 2/3 by dividing the numerator and denominator by their HCF which is 4
The HCF of 40 & 12 is... 4
The HCF is 4. 16/4 is 4, 12/4 is 3
The HCF of the given numbers is 4
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.
