“-还有一个多选 5^a is the greatest prime factor of 1500, and 3^b is the greatest prime factor of 333,333,000 或是333,333 , 好像这样的数字, a和b are integer, 然后多选, 有 a>b, a=b, 2a>5b 我也不知道怎么选, 我最想选的是the ans can not be determined by the information 哭"
333333=3*3*7*11*13*37....greatest prime factor is 37.... 37必然不能是3的倍数。。。
