[자유 기사] [자유 기사] 주민등록번호의 비밀??!!(오류검증번호)

다음 사진을 봅시다. 이 사진은 제가 직접 그린 그림인데,주민등록번호의 각 자리를 나타낸 것입니다.

위의 그림중 1번 부분(A,B,C,D,E,F)은 자신이 태어난 년,월을 나타냅니다.

2번 부분:여자,남자

3번 부분:출생 지역

을 나타냅니다.

4번 부분은... 절대 다른 수가 올 수 없는 오류검증번호입니다!!

'오류검증번호'란, A부터 M까지 순서대로 2,3,4,5,6,7,8,9,2,3,4,5를 곱한 뒤, 11로 나눈 나머지입니다.

 

예를 들면, 주민등록번호가 [201225-305157*]일 때 *를 구해 봅시다.

{\color{Purple} (2 imes 2+0 imes 3+1 imes 4+2 imes 5+2 imes 6+5 imes 7+3 imes 8+0 imes 9+5 imes 2+1 imes 3+5 imes 4+7 imes 5)나누기 11이므로 답은 15...2로 오류검증번호는 2입니다!(수식 입력기에서 나누기 기호를 결국 못찾음)

 

문제입니다!!!! 이것은 파이의 주민등록번호이다.

[201228-3598*7#]

*가 1~9라고 할 때 #의 경우 중 가장 작을 때를 조사해 비밀댓글로 알려주시오.

태그
#수학 #자유 #기사 #주민등록번호 #오류검증번호
