Question

In Java, create a two-part program. The first takes a user inputted number and lists the factors. The second, lists all the prime numbers up to the integer the user inputted.

Answer 1

The question requires making a Java program that lists the factors of an inputted number and then lists all prime numbers up to that number.

Step-by-step explanation:

The question involves creating a two-part program in Java that deals with concepts from both mathematics and programming. In the first part, the program should take a number inputted by the user and list all its factors. The second part should list all prime numbers up to the given integer.

Part 1: Listing Factors

To list the factors of a number, you would need to iterate through all integers from 1 to the number itself, checking if the number is divisible by each integer without leaving a remainder.

Part 2: Listing Prime Numbers

To list all prime numbers up to a certain integer, you can use the Sieve of Eratosthenes algorithm, or a simpler method where you check each number for primality by attempting to divide it by all smaller numbers (excluding 1 and itself). To be considered prime, it should not be divisible evenly by any of these numbers.
