15
21 and 28 are the two multiples.
Consecutive numbers can't both be multiples of 7. The LCM of consecutive numbers is their product. 14 and 15 are consecutive numbers whose LCM is a multiple of 7 that is greater than 200.
Multiples of any number greater than one are composite.

The first action sequence in the flow chart is to remove all multiples of 2 from numbers greater than 2. The next sequence removes removes all multiples of 3 from all numbers greater than 3. The third sequence removes all multiples of 5 from the remaining numbers greater than 5. The fourth sequence removes all multiples of 7 from the remaining numbers greater than 7. Additional sequences are added as needed to remove multiples of as many primes as desired in ascending order.
