What is the difference between factor pairs and distinct factor pairs?
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.

What is the difference between a prime and a composite number?
A prime number is a positive integer that has no positive integer factors other than one and itself, and a composite number is a positive integer that have two or more positive integer factors.
What is the difference between positive and prime factors?
Factors are just numbers. Some numbers are positive, some negative. Some numbers are prime, some composite. A prime factor is always positive, but a positive factor is not always prime.
What is the third smallest natural number that has exactly four distinct positive factors?

If told that 'q' 'p' and 'r' are distinct primes and that there exists 'n' such that 'n equals p x q x r' How many positive factors of 'n' are there and How do you determine what they are?
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.
How many distinct factors does 45 have?
Six distinct factors Two distinct prime factors
What is the difference between prime and compostie number?
