# Prime Number Generator to Create List of Prime Numbers

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.

## Prime Number List Generator

Create a list of prime numbers for a given range, and formatted either for copying and pasting or for printing.

If a Data Record is currently selected in the "Data" tab, this line will list the name you gave to that data record. If no data record is selected, or you have no entries stored for this calculator, the line will display "None".

#### Prime number list options:

Tap one of the two options to indicate how you would like to select the set of prime numbers. The next line will change to match your selection.

The left-hand option will generate a list from the number 2 through the number of primes you enter in the field.

The right-hand option will create a set of primes between the two numbers you enter.

Note that the maximum first number of primes is 10000 and the maximum ending between entry is 104730.

### Help and Tools

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".
