你能找出三个自然数,使它们的和与积相等。利用这个结果来解下题:将从3至11共九个自然数,分别填入三角形周界上九个黑点子位置上。要同时满足三点:(1)每边上四数之和(共三个)是三个相邻的二位质数。(2)这三质数和除以7的余数是6。(3)这三质数积除以7,余数也是6。 You can find three natural numbers that make their sum equal to their product. Use this result to solve the problem: a total of nine natural numbers from 3 to 11, respectively, fill the triangle on the nine black spots on the perimeter. To satisfy three points at the same time: (1) The sum of the four numbers on each side (three in total) is three contiguous two prime numbers. (2) The remainder of the three prime numbers and the remainder divided by seven is six. (3) The three prime product divided by 7, the remainder is 6.
