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.
HCF(98, 182) = 14.
It is: 14
The GCF is 2.
HCF is the highest common factor of two or more numbers. HCF of 20 and 200 is 20.
The HCF is 14.
The GCF is 10.
The HCF of 14 and 24 is 2.
2
HCF = 14
The GCF is 14.
The HCF is 7.
The GCF is 20.
