Algorithm to find whether a number is prime or not?
check if 2 divides the Numbercheck if 3 divides the Numbercheck if 5 divides the Number...check if any prime numbers less than the square root of the Number divide the NumberIf any do, the Number is composite; otherwise the Number is prime.This is called the Sieve of Erasthenes.An easy way to check if a prime number divides the Number in base ten (if you don't have a calculator) is to add or subtract 1 or 3 times the prime number to the Number, so that the sum or difference is a multiple of ten (if the prime number isn't 2 or 5). Knock off the zero. If the prime number divides the new number, it also divides the Number; otherwise it doesn't.
