How many odd number(s) is / are divisible by 3 but not divisible by 5 from 1 to 1000?1至1000这1000个整数中有多少个奇数能被3整除,却不能被5整除? 相关知识点: 试题来源: 解析 134.[(10000)/3]-[(1000)/6]-[(1000)/(15)]+[(1000)/(30)]=333-166-66+33=134. ...
This gives us 105* 2=210 which is divisible by 3, 5, and 7 and is also between 200 and 300. The number is 210.若一个数能被3,5和7整除,那么它一定能被它们的最小公倍数整除.因为3,5 和7除了1之外没有共同的因子,所以这三个数的最小公倍数是它们的乘积.因为3* 5* 7=105不在200到300...

Step 1: 32 3 rArr 32 - 3 xx 5 = 17 [therefore 5 is the negative osculator of 17] therefore 323 is divisible by 17.
divisible到底是能被除尽还是整除的意思题目是这样的说n is divisible by both 5and 7 then n must also be divisible by 但是我觉得要是说是像字典里一样解释为除尽的话 那不是应该也能被70除尽么? 答案 能被5和7除尽的必定能被35除尽,但不一定能被70除尽,要能被70除尽,需要同时能被5,7,2除尽相...
