How many distinct prime factors does have?

Guide / Hint

Hint 1: The distinct prime factors are the base numbers in the prime factorization.

Hint 2: Look at the bases of . They are 2, 3, and 5.

Hint 3: Count the number of distinct bases to find the answer.

Solution

Step 1 (Understand Prime Factors): The prime factors of a number are the distinct prime numbers that divide the number. We are given the number already in its prime factorization form:

Step 2 (Identify Distinct Bases): The bases in this prime factorization represent the prime factors of the number. The distinct bases are:

Step 3 (Conclusion): There are exactly 3 distinct prime factors. The answer is 3.
