To work this out, you have to split the numbers into their prime factors:
32 = 2x2x2x2x2
98 = 2x7x7
The next step is to spot any common prime factors. In this case both numbers have a 2 as a prime factors. Thus the HCF of 32 and 98 is 2.

Eight and 32's highest common factor is eight.
I believe you mean GCF. If that is the case, then the Greatest Common Factor of 12 and 32 is 4.
2, 7, and 89 are three prime numbers whose sum is 98.
