问一道VB编程题

Option Base 1

Private Sub Command1_Click()
a = InputBox("请输入一个正整数")
b = InputBox("请输入一个正整数")
Text3.Text = "您输入了" & a & "和" & b
Dim d() As Integer
If a > b Then
c = Val(a)
Else
c = Val(b)
End If
ReDim d(c) As Integer
For i = 1 To c
If Val(a) Mod i = 0 And Val(b) Mod i = 0 Then
d(i) = i
Text1.Text = d(i)
End If
Next i
g = Int(Text1.Text)
f = (a \ g) * (b \ g) * g
Text2.Text = f
End Sub

给你写一个函数，自己调用：

'最大公约数

Function GYS(ByVal num1 As Integer, ByVal num2 As Integer)As Integer

    While (num1<>num2)

    if (num1>num2) then

    num1=num1-num2

    else

    num2=num2-num1

    end if

    Wend

  return num1

End Function

'最小公倍数：

Function GBS (ByVal num1 As Integer, ByVal num2 As Integer, ByVal gbs As Integer)

  return num1*num2/gbs

End Function

'主函数调用

'求最大公约数：GYS(4,2)

求最小公倍数： GBS(4,2,GYS(4,2))
