Alright, so I've been given this problem: "What is the biggest prime number between 23456 and 123456." At first glance, it seems pretty straightforward, but I need to make sure I understand what's being asked. I need to find the largest prime number within this range.
First things first, I need to recall what a prime number is. A prime number is a natural number greater than 1 that has no positive divisors other than 1 and itself. So, numbers like 2, 3, 5, 7, and so on are primes because they can't be divided evenly by any other numbers except 1 and themselves.
Now, the range given is from 23456 to 123456. That's a pretty large range, so checking each number individually isn't practical. There must be a smarter way to approach this.
I know that prime numbers become less frequent as numbers get larger, but they still appear infinitely. However, within a specific range, there should be a finite number of primes. My goal is to find the largest one in this particular range.
