To figure out the HCF of 28 and 60, split them up into their prime factors: 28 = 2x2x7 60 = 2x2x3x5 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: 2x2 = 4 Therefore 4 is the HCF of 28 and 60.
The HCF of 12 and 60 is 12
hcf = 4 and lcm = 420
The GCF is 28.
The GCF is 6.
The GCF is 20.
The GCF is 12.
The GCF is 10.
The GCF is 4.
HCF is the highest common factor of two or more numbers. One such pair which has 60 as their HCF can be: 120 and 180.
The GCF is 12.
The GCF is 12.
