英语翻译
find the sum of all prime numbers between 1 and 100 that are simulataneously 1 greater than a multiple of 1 less than a multple of 5
求100以内比4的倍数多1,同时比5的倍数少1的所有的质数的和.
2 3 5 7 11 13 17 19 23 29
31 37 41 43 47 53 59 61 67 71
73 79 83 89 97
5的倍数少1的质数作为突破口,因5的倍数尾数为0,5,比它少1,会是9或4,4不可能,所以找尾数是9的质数19,29,59,79,89
其中,比4的倍数又多1的有:29,89
所以答案是:29+89 =118
刚给别人回答过...
再问: 这里没有提到4的倍数
再答: Find the sum of all prime numbers 1and 100 that are simultaneously 1 greater than a multiple of 4 and 1 less than a multiple of 5 希望你没有打错题目....
