수학동아 - 폴리매스
함께 풀고 싶은 문제
창의력을 기를 수 있는 수학 문제 또는 퍼즐을 내는 곳입니다.
[창의 퍼즐] [정수] 8렙! 기념 (그렇게 간단하지 않은) 소인수분해 문제
나의 현재 포인트는 100040점이다.
이를 거듭제곱을 사용하지 않고 소인수분해하고,(예:50=2*2*5*5)
그 소인수를 다 더한 다음,(2+2+5+5=14)
또 그 수를 소인수분해하고,(14=2*7)
그 소인수를 다 더한다.
이런 과정을 반복해 마지막에 소수가 될 때까지 한다.
이때, 소수가 될 때까지 소인수분해를 하는 수와, 그 마지막 소수의 곱을 구하여라.
(2+7=9, 9=3*3, 3+3=6, 6=2*3, 2+3=5, 소인수분해 횟수 4번, 마지막 소수=5, 곱하면 20과 같이 풀이 다 써야 합니다!)
