A set of numbers can only have one GCF. 6, 12 and 18 have a GCF of 6. 16, 32 and 48 have a GCF of 16. 25, 50 and 75 have a GCF of 25. The GCF of 6, 16 and 25 is 1.
12, 24, 120
12, 24, 1200
The numbers are 2, 4 and 6.
To calculate the GCF you first have to split the numbers into their prime factors: 28 = 2x2x7 12 = 2x2x3 20 = 2x2x5 The next step is to identify any common factors. In this case, all three numbers have two 2s. Multiply these together and you get 4. Therefore the GCF of 28, 12 and 20 is 4.
12 and any three multiples of 12.

How about: 12, 16 and 24
The GCF of 24 and 36 is 12. The GCF of 60 and 96 is 12. The GCF of 12 and 120 is 12.
