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.
14
You get 14.
Two distinct prime factors
The number 152 can be factored into 2 x 2 x 3 x 5, which has 3 distinct prime factors. The number 643 can be factored into 2 x 2 x 2 x 2 x 2 x 2 x 2, which has 1 distinct prime factor. Therefore, the positive difference between the number of distinct prime factors of 152 and 643 is 3 - 1 = 2.
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.
A prime number has only two factors which are itself and one.
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.
The only number between 30 and 40 with distinct prime factors which add up to 12 is 35.
1 and 31, it is a prime number.
