Private Sub Form_Click() Dim i% For i = 1000 To 1500 If i Mod 3 = 2 And i Mod 5 = 3 And i Mod 7 = 2 Then Print i End If Next i End Sub

i=1073,1178,12831388,1493

3a+2=5b+3=7c+2=Y

3a=7c=5b+1

可得Y-2是3的倍数，也是7的倍数，并且y-2的个位不是1就是6

那么可得Y-2是21的倍数。那么找998到1498之间复合21的倍数且个位是1或6的数

21*50=1050

21*49=1029

21*48=1008

21*47=987

21*51=1071

所以Y-2=1071得，Y=1073

所以这个最小的数是1073
