解析 C 12=22×3,15=3×5,而n能够被12和15整除,那么n就至少具有因子22,31,51,选项中哪个数能够由上面因子中的一个或者几个相乘得到,那么这个数就一定能够整除n;25具有两个因子5,不行;16具有4个因子2,也不行;30=2×3×5,2,3,5全部可以为n的因子,因此30一定能够整除n,选择C。
英语翻译请翻译这段话:f x is divisible by y,then every prime factor in y must be found in x.Example:If 504 is divisible by y,then y could be 168 (2^3 * 3 * 7),or 21 (3 * 7),or 4(2^2),or many other things.Y could not,however,be equal to 10
Since the greatest common factor of 12 and 20 is 4, the least common multiple is 12 * 20 ÷ 4 = 60. (Notice that 60 is 12 * 5 and also 20* 3.) Notice that the only integer among the choices that is a factor of 60 is (A) 15....
