357*1,179*35最小
753*9,751*93最大
再问：对不起，379*15比他还小不过就一个错~~ 最佳吧！

1 3 5 7 9选数字,怎样最小 0、1、2、5四个数字中,选三个数字组成一个最小三位数,是他同时是2、3和5的倍数.这个最小是? 一道数学题,最小乘积用1、3、5、7、9这5个数字组成一个两位数和一个三位数,并使它们的乘积最小,这个最小的乘积是多少? 用0,1,2,3,4,5,6,7,8,9这九个数字组成质数,每个数字只能用一次,最小的质数和是多少? 在0~9的十个数字中,任意选择四个数字,组成最大的数和最小的数.如选1,3,7,8四个数字,最大的数是8731 用1、2、3、4这四个数字组成两个两位数,1、怎样使这两个数的积最小,最小的积是多少? 3,5,7,8,9组成一个三位数和两位数,怎样组时积最大怎样组时积最小?怎样给孩子讲在0,5,4,9四个数字中挑出三个数字,按要求写出三位数.(1)有因数3的偶数,(2)2、3、5的最小倍数. 在5、7、9、1、0这五个数字中,选出其中的四个数字组成四位数,最大的偶数是多少?最小的奇数是多少? 在5、7、9、1、0这五个数字中,选出其中的三个数字组成三位数,最大的偶数是多少?最小的奇数是多少从0,1,2,5,9这五个数字中选出四个数字组成一个能同时被2,3,5整除的最小四位数是几? 在0,5,4,9四个数字中挑出三个数字,按要求写出三位数.《1》2,3,5的最小倍数?
