PRIME NUMBERS |
|
|
Prime numbers are numbers whose only divisors are one and itself. For example, 23 is a prime number because its only divisors are 1 and 23. Prime numbers have captured the hearts of many mathematicians for centuries. Euclid proved that there is no largest prime number. During 18th century, mathematician Christian Goldbach (1690-1764) wrote to Leonhard Euler that he believed it could be shown that every even integer greater than 2 is the sum of 2 primes. For example, 30 = 23+7 and 36 = 13+23. Until now, this conjecture has neither been proved or disproved.
