30 is the first with three distinct prime factors.
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.
1 and 31, it is a prime number.
You get 14.
There are an infinite number of them. 8 has three prime factors, 30 is the first with three distinct prime factors.
Two distinct prime factors

Find the prime factorization. Identify the distinct prime factors. Add them up.
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.
1 and 31, it is a prime number.
