This question arose at a job-interview site:
Find all numbers divisible only by 3, 5 and 7. For instance, 35 = 5 × 7 is included in the set, but 30 = 2 × 3 × 5 is not because of the factor of 2.
Your task is to write the requested program and determine how many numbers in the set are less than a million. When you are finished, you are welcome to read or run a suggest solution, or to post your own solution or discuss the exercise in the comments below.
