Most Naive Primality Tester
Use numbers with 18 or fewer digits, do not use commas.
If you enter an 18-digit number that happens to be prime, it may
take a minute (or 5!?) to verify its primality by this naive
algorithm, since after all as many as 500,000,000 trial divisions will
have been performed. So be patient...?
