For the sake of practice I created a node that can check if a number is a prime number and find prime numbers from a list. If I’m honest I’m not exactly expecting it to be ever useful in a regular Dynamo script, but I thought I’d share it anyway.

You can give a number or list of numbers as an input. And it will give you a list of the numbers from the input that are prime and simply give a boolean on whether a number is prime or not.

Credit where credit is due: I did use Clockwork’s `List.AnyTrue`

node.
