Prime Numbers

Prime numbers are all the natural numbers with exactly two divisors. Therefor number 1 is not a prime number and the number 2 is the only even prime number. Euclid has proved that there is an infinite number of prime numbers. And it is also proven that there are gaps of any size in the sequence of prime numbers.

If the difference between the upper and the lower limits exceeds 50000 the range is automatically limited to 50000.

If you want to know what the 1000th prime number is, you can also get a numbered list. The highest index is 10000. You can choose between a line-by-line display and a list of the numbers one below the other. To switch between the two displays, click on the legend to the right.
