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.
Since 17 is a prime number, there is only one pair of distinct positive integer factors of the number:17 x 1 = 17
1 and 31, it is a prime number.
A prime number is a number with just two distinct positive integer factors - the number itself, and 1. For example, 7 is prime, but 9 is not.
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.
Oh, dude, the positive difference between the number of distinct prime factors of 15 squared (225) and 64 cubed (262,144) is like 4. Prime factors are like those VIP numbers that can't be divided by anything except 1 and themselves. So, 225 has 2 distinct prime factors (3 and 5), and 262,144 has 1 distinct prime factor (2). Subtract 1 from 2, and you get 1. Wow, math can be fun, right?

30 is the first with three distinct prime factors.
There are an infinite number of them. 8 has three prime factors, 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.

Since 17 is a prime number, there is only one pair of distinct positive integer factors of the number:17 x 1 = 17
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.
