Random Number Generator

How the calculation works

Choose a minimum, a maximum and how many numbers you need. Numbers are drawn using your browser’s secure random generator. Turn on ‘No duplicates’ to draw without repeats, such as for a raffle.

Formula used

Random integer = minimum + random value × (maximum − minimum + 1)

Example

Choosing 5 numbers between 1 and 100 might return 56, 19, 58, 33 and 89.
