Definition of Prime Number: A prime number is a positive integer that is only divisible by two factors: 1 and itself. In contrast, a composite number is a number that is divisible by numbers other than 1 and itself - in other words, not a prime number.
Facts About Prime Numbers:- The only even prime number is 2.
- There are an infinite number of prime numbers.
- Consecutive odd primes are known as "twin primes", such as 3 and 5, 11 and 13, or 521 and 523. There might be an infinite number of twin primes.
- The only "triplet primes" are 3, 5, and 7.
- Primes with a difference of four, such as 3 and 7 or 19 and 23, are sometimes called "cousin primes" and those with a difference of six, such as 5 and 11 or 47 and 53, are sometimes called "sexy primes".
- The number 1 was once viewed as a prime number, but now it is considered neither prime nor composite.
- One of the largest known primes is 243112609-1, which is 12,978,189 digits long.
