Challenge #187: Generate Prime Numbers

Highlighted

Looks like my initial inclination to run through all possible combinations was virtually identical to many of the previous entries. This is the naïve and most obvious approach.

 

For fun, I ran the workflow for larger values of N to see how long it took:

N = 1000 - 2.1 seconds (168 primes)

N = 10,000 - 79 seconds (1,229 primes)

Assuming the prime numbers divided by 2 and divided by 3 would result in a decimal for both answers, I used the formula tool and Filter to check for these scenarios with the understanding 2 and 3 are the exceptions to the rule.

Here's my solution:

This works well for any set of numbers. The range should be written in the text input.

Very basic attempt at it but it seems to work nicely enough.
