The Prime Number Spiral (a.k.a. the Ulam Spiral) is formed by marking the prime numbers in a spiral arrangement of the natural numbers. This is software is for exploring the Prime Number Spiral.
calculates the prime numbers 1..N, tells you if N is prime etc.
Prints tables of primes.
Computes the prime just below or above N.
It is useful in computing optimal Hashtable sizes.
Java source included.

Factorizer may be used:
(1) to get the prime decomposition of all numbers in a range of numbers
(2) to get all factors of a single number or all factors of all numbers in a range
(3) to find only the prime numbers in a range of numbers
(4) to find...
This application illustrates the notion of an integer's factors, and of the related property of integers called primeness, or primality. An integer is called prime if it is the product of only one distinct pair of integers. For example, 11 is prime...
