**What are Prime Numbers?**

Prime numbers are a basic concept in mathematics. They are natural numbers greater than 1 that can only be divided by 1 and themselves, leaving no remainder. In other words, prime numbers have exactly two distinct factors – 1 and the number itself. Some well-known examples include 2, 3, 5, 7, 11, and so on. Prime numbers play an important role in number theory and various fields of mathematics and computer science. They are essential building blocks for many mathematical concepts and in cryptography, where they are used to secure data transmission. Understanding prime numbers is not only essential for mathematicians, but also has practical applications in the modern world.

**What is the difference between prime numbers and co-prime numbers?**

**Prime numbers:**

Prime numbers are a fundamental concept in number theory. A prime number is a positive integer greater than 1 that has exactly two distinct positive divisors: 1 and itself. In other words, it is not evenly divisible by any number other than these two. Examples of prime numbers are 2, 3, 5, 7, 11, etc. Prime numbers are unique in that they cannot be formed by multiplying two small positive integers.

**Co-Prime Numbers (Relatively Prime):**

Co-prime numbers, also known as relatively prime or mutually prime numbers, refer to two or more positive integers that share no common positive integer divisor other than 1. In other words, the greatest common divisor (GCD) of co-prime numbers is 1. For example, 15 and 28 are co-prime because their GCD is 1. Co-prime numbers are not necessarily prime themselves; They may have other divisors, but they share no common divisor other than 1.

**Differences:**

- Prime numbers are fixed integers with exactly two divisors, 1 and themselves, while co-prime numbers are pairs of integers with a GCD of 1.
- Prime numbers are a subset of the natural numbers, while co-prime numbers can be any pair of positive integers.
- Prime numbers are usually studied individually and have unique properties, whereas co-prime numbers are considered in pairs and are relevant in a variety of mathematical contexts, including modular arithmetic, number theory, and cryptography.
- Where there are an infinite number of prime numbers, there are also an infinite number of co-prime pairs, making co-prime relationships more varied and abundant.

**What is the lowest prime number?**

2 is a prime number because it has only two factors: 1 and itself. All other even numbers have at least one additional factor: 2.

**Which is the largest known prime number?**

The largest known prime number as of September 30, 2024 is 282,589,933 – 1. It contains 24,862,048 digits and was discovered by Patrick Laroche of the Great Internet Marsan Prime Search (GIMPS). Mersenne primes are prime numbers of the form 2ⁿ – 1, where n is a prime number. GIMPS is a distributed computing project that assigns small tasks to volunteer computers to search for Marsan primes. Finding larger and larger prime numbers is important for several reasons. For example, prime numbers are used in cryptography to create secure encryption algorithms. They are also used in number theory to study the properties of numbers.

**Last Words**

The list of prime numbers from 1 to 100 provides a basic insight into the world of mathematics. These numbers, defined as positive integers greater than 1 with exactly two distinct positive divisors, have intrigued mathematicians for centuries. From the smallest prime, 2, which is the only even prime, to the largest prime in this range, 97, prime numbers exhibit an interesting array of patterns and properties. They serve as the basic building blocks for all other natural numbers and find applications in cryptography, number theory, computer science, and beyond.
