More ways

Deleting consecutive columns like 1 - 100

Sub Sample()
    With Sheet1
        'A:CV
        .Columns(ReturnName(1) & ":" & ReturnName(100)).Delete Shift:=xlToLeft
    End With
End Sub

'~~> Returns Column Name from Col No
Function ReturnName(ByVal num As Integer) As String
    ReturnName = Split(Cells(, num).Address, "$")(1)
End Function

Deleting non consecutive columns like 1, 3, 5

Sub Sample()
    With Sheet1
        'A:A,C:C,E:E
        .Range( _
                ReturnName(1) & ":" & ReturnName(1) & "," & _
                ReturnName(3) & ":" & ReturnName(3) & "," & _
                ReturnName(5) & ":" & ReturnName(5) _
               ).Delete Shift:=xlToLeft
    End With
End Sub

Function ReturnName(ByVal num As Integer) As String
    ReturnName = Split(Cells(, num).Address, "$")(1)
End Function

'**Another way**

Sub Sample()
    Dim Rng As Range

    With Sheet1
        Set Rng = Union(.Columns(1), .Columns(3), .Columns(5))
    End With

    Rng.Delete Shift:=xlToLeft
End Sub
