이 문제는 오일러 프로젝트 118번과 같은 개념이라고 볼 수 있나요?
문제 내용이 이해가 잘 안되네요;;

앗 감사합니다..그런데 0부터 9까지의 숫자가 모두 쓰여야 하는 건 자연수 N이 아니라 소인수들 아닐까요?
저는 아래와 같이 생각했습니다
N = 701 x 89 x 65 x 43 x 2
합성수도 있지만 소수라고 치면 이런 형태의 경우를 구하는 것으로 이해했는데, 혹시 원파님이 말씀해주신 내용에 따라 경우를 하나 예시로 들어주실 수 있나요??

음..그건 저도 구하지 못했는데,
다시 보니 솔바람님이 말한 조건이 더 일리가 있는 것 같네요
