gmat数学题.if n is a positive integer and n^2 is divisible by 72,then the largest positive integer that must divide n is 答案是24, 扫码下载作业帮搜索答疑一搜即得 答案解析 查看更多优质解析 解答一 举报 72=8*9=2*2*2*3*3若72a=2*2*2*3*3a=n^2所以n最小为2*2*3=12,a=2. 解析看...
个人看法。理解一下The largest integer that must divide n, 表示的是n一定含有的最大的因子，也就是n取最小值时也一定含有的最大因子。n^2=72x，把72分解，n^2=2^3*3^2*x；n是正整数，那么n^2必然要能开方，也就是说x至少含有一个2，n最小值是不是就是2^2*3=12。12最大的因子就是它本身12...
