100以内3倍数有哪些

java编程 求1——100之间3的倍数和: public class Sum{
public static void main(String[] args){
int sum=0;
for(int i=1;i<=100;i++){
if(i%3==0){
sum=sum+i;
}
}
System.out.println(sum);
}
}

100以内2和3的公倍数有那些: 2和3互质，所以2和3的最小公倍数是2×3=6
100÷6商是16
所以有16个，分别是：6,12,18,24,30,36,42,48,54,60,66,72,78,84,90,96

输出100以内所有3的倍数怎么编程: int sum = 0;for(int i = 1; i < 101; i++){ if(i % 3 == 0) sum += i;}sum就是1~100中是3的倍数的所有整数之和

编程题目：求1-100以内的所有3的倍数之和: 用什么语言？

在一百以内的数中既是三的倍数又是九的倍数的数有哪仙: 9本身就是3的倍数，所以。。只要选择9的倍数即可：9/18/27/36/45/54/63/72/81/90/99

用VB编写“求100以内3的倍数”的程序: 窗体中创建三个check按钮，分别选中表示2的，3的，5的倍数
一个combo控件用于显示结果
Public m As Integer, n As Integer, k As Integer
Private Sub Check1_Click()
m = Check1.Value
n = Check2.Value
k = Check3.Value
Combo1.Clear
Call js(m, n, k)
End Sub
Private Sub Check2_Click()
m = Check1.Value
n = Check2.Value
k = Check3.Value
Combo1.Clear
Call js(m, n, k)
End Sub
Private Sub Check3_Click()
m = Check1.Value
n = Check2.Value
k = Check3.Value
Combo1.Clear
Call js(m, n, k)
End Sub
Sub js(mm As Integer, nn As Integer, kk As Integer)
Dim i As Integer
If mm = 1 Then
If nn + kk = 0 Then
Combo1.Text = "2的倍数"
For i = 1 To 100
If i Mod 2 = 0 Then Combo1.AddItem Str(i)
Next
ElseIf nn = 1 And kk = 0 Then
Combo1.Text = "2和3共同的倍数"
For i = 1 To 100
If i Mod 2 = 0 And i Mod 3 = 0 Then Combo1.AddItem Str(i)
Next
ElseIf nn = 0 And kk = 1 Then
Combo1.Text = "2和5共同的倍数"
For i = 1 To 100
If i Mod 2 = 0 Or i Mod 5 = 0 Then Combo1.AddItem Str(i)
Next
ElseIf nn = 1 And kk = 1 Then
Combo1.Text = "2,3,5的倍数"
For i = 1 To 100
If i Mod 2 = 0 And i Mod 3 = 0 And i Mod 5 = 0 Then Combo1.AddItem Str(i)
Next
End If
Else
If nn = 1 And kk = 0 Then
Combo1.Text = "3的倍数"
For i = 1 To 100
If i Mod 3 = 0 Then Combo1.AddItem Str(i)
Next
ElseIf nn = 0 And kk = 1 Then
Combo1.Text = "5的倍数"
For i = 1 To 100
If i Mod 5 = 0 Then Combo1.AddItem Str(i)
Next
ElseIf nn = 1 And kk = 1 Then
Combo1.Text = "3和5共同的倍数"
For i = 1 To 100
If i Mod 3 = 0 And i Mod 5 = 0 Then Combo1.AddItem Str(i)
Next
End If
End If

数学指导上的题：100以内同时是3和5的倍数的最大奇数是( ): 100以内同时是3和5的倍数的最大奇数是75

15*奇数<=100

100以内30的倍数有: 100以内，30的所有倍数。
