Seven distinct factors.
7 factors. They are: 1, 2, 4, 8, 16, 32, 64
Not two DISTINCT prime factors, no. For example, 64 = 2^6 only has prime factor 2. All even numbers which are not a power of 2 must have at least two distinct prime factors, however; one of them will, of course, be 2.
64 and 96 have the longest prime factorizations in that range. If you're asking about distinct prime factors, quite a few are tied with three.
64 has only one prime factor: 2
