## Some Prime Quality Facts!
Time for some prime facts roundup, or prime numbers round up to be arithmetically exact. Take the following sciensational mathematics fact: The largest prime number is 9,808,358 digits long; more than the number of atoms in the universe. The basics first. What is a prime number? It’s when a number can be divided only by itself, with no remainder, and by the number 1. You know, 1, 3, 5, 7, 11… The list literally goes on. The fact above has another fascinating fact in itself: the number of atoms in the universe. Though it is a discussion for a different post altogether, let’s just know that the number of atoms in the universe can be written in just 80 digits. That makes our biggest prime find even greater. Another sciensational maths fact says: 2 and 5 are the only primes that end in 2 or 5. That is true for all decimal numbers for all known primes! « Previous: Some Diamond Facts are Forever!» Next: Over the Moon facts |
