Challenge #187: Generate Prime Numbers

[johnemery]

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.
