66, 90, & 115 Reduce each number to its prime factors. Hence 66 = 11,3,2 90 = 18,6 = 3,6,6 = 3,3,3,2,2 115 = 5,23 The HCF between 66, & 90 is 3,2 = 6 There is no common factor between 115 and 66,90.
The GCF is 6.
The HCF of 4 and 90 is 2.
The GCF is 18.
The GCF is 30.
HCF(160, 90) = 10.
At least 2 or more numbers are needed to find their hcf but 66 as a product of its prime factors is: 2*3*11 = 66
11
The HCF of 66 and 121143 is 33
