The easiest way to do this is to split the numbers down into their prime factors:
14 = 2x7
20 = 2x2x5
The next step is to spot any common prime factors. In this case both numbers have a 2 as a prime factor. Therefore, the HCF of 14 and 20 is 2.
The GCF is 10.
The HCF of 14 and 24 is 2.
2
HCF(98, 182) = 14.
HCF = 14
HCF is the highest common factor of two or more numbers. HCF of 20 and 200 is 20.
The GCF is 14.
It is: 14
The HCF is 14.
The HCF is 7.
The GCF is 20.
HCF(56, 98, 168) = 14
