Prime Number Generator to Create List of Prime Numbers

Prime Number List Generator Sign

This calculator will allow you to build a set of primes based on your selections and display it in a delimited format of your choice, for copying and pasting and/or importing into other document types (word processing, spreadsheet, etc.).

You can create a set of primes for as high the first 10,000 primes, or a set between any number and 104,730 (to check to see if a number greater than 104,730 is prime, please visit the prime number checker).

For example, you could create a list containing the first 100 prime numbers, or you would create a list of primes between 1 and 100 (25 primes).

Finally, the prime number generator even gives you the option to create a printer-friendly prime numbers chart containing your custom list.

Help and Tools

Adjust Calculator Width:

Move the slider to left and right to adjust the calculator width. Note that the Help and Tools panel will be hidden when the calculator is too wide to fit both on the screen. Moving the slider to the left will bring the instructions and tools panel back into view.

Also note that some calculators will reformat to accommodate the screen size as you make the calculator wider or narrower. If the calculator is narrow, columns of entry rows will be converted to a vertical entry form, whereas a wider calculator will display columns of entry rows, and the entry fields will be smaller in size ... since they will not need to be "thumb friendly".

Show/Hide Popup Keypads:

Select Show or Hide to show or hide the popup keypad icons located next to numeric entry fields. These are generally only needed for mobile devices that don't have decimal points in their numeric keypads. So if you are on a desktop, you may find the calculator to be more user-friendly and less cluttered without them.

Stick/Unstick Tools:

Select Stick or Unstick to stick or unstick the help and tools panel. Selecting "Stick" will keep the panel in view while scrolling the calculator vertically. If you find that annoying, select "Unstick" to keep the panel in a stationary position.

If the tools panel becomes "Unstuck" on its own, try clicking "Unstick" and then "Stick" to re-stick the panel.
