A prime number is a whole number that has only two distinct factors: 1 and the number itself. A composite number has at least three distinct factors.
289 does.
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.
It is 27720.
