The difference is one.
The definition of a prime is an integer that has two positive factors, one and itself. These are two distinct factors. One only has one positive factor. Thus it's not a prime.
Twelve distinct factors.
Three distinct prime factors.
Distinct prime factors are the prime factors that are distinct (or different) from each other. A list of distinct prime factors is a list of one of each different prime number that is a factor. For example, the prime factors of 8 are 2, 2, and 2. The only distinct prime factor is 2, which occurs multiple times.
Proper factors do not include one and the number itself.
It is 8.

The difference between factors and coefficient is very distinct. A factor is a quantity which is multiplied with another to give a particular number as the result. A coefficient on the other hand is a multiplier that measures property.

5 - 2 = 3
The difference is between factor pairs and distinct factors. With square numbers, one of the factor pairs will be the same number twice. When listing the distinct factors, that number is only listed once.
If p, q and r are distinct primes and n=pxqxr then n will have 8 factors, all of which will be positive since prime numbers are all positive, which are: n(pqr), pq, pr, qr, p, q, r and 1. Here there were 3 distinct primes so the number of positive factors is 2^3. In general if you had p distinct primes then you would have 2^p positive factors.

A prime number is a positive integer with two factors: one and the number itself. A composite number is a positive integer with more than two factors.
Blood Type O has no Anti Rh factors. O+ blood is positive for Rh Antibodies.
Some prime factorizations have repeated factors. The prime factorization of 72 is 2 x 2 x 2 x 3 x 3. The distinct prime factors of 72 are 2 and 3.
125 has the following factors: 1,125,5 & 25. Therefore there are 4 factors.
