4) There are three positive integers less than 100. One is a prime number, one is a composite number, and one is neither a prime number nor a composite number. Find the maximum possible value of the product of these three numbers.
To find the maximum possible value of the product of three positive integers less than 100, where one is a prime number, one is a composite number, and one is neither a prime number nor a composite number, we need to identify the largest numbers in each category.
1. Neither prime nor composite: The number 1 is neither prime nor composite[1].
2. Prime number: There are 25 prime numbers less than 100, with the largest prime number being 97[2].
3. Composite number: There are 74 composite numbers between 1 and 100, with the largest composite number being 100[3].
Now, we can calculate the maximum possible value of the product of these three numbers:
1 x 97 x 100 = 9700
Therefore, the maximum possible value of the product of these three numbers is 9,700.
