Use the Pad and CombineColumns funtions

Text.PadStart(Text.From([Column1], "en-GB"), 8, "0")

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMjG1tDA1tjBUgAAlHSVDILZQitWJVjI1MjUwNATxjYDYEixmbGQBETIBKTVQio0FAA==", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type text) meta [Serialized.Text = true]) in type table [Column1 = _t, Column2 = _t, Column3 = _t]),
    Type = Table.TransformColumnTypes(Source,{{"Column1", Int64.Type}, {"Column2", Int64.Type}, {"Column3", Int64.Type}}),
    Pad1 = Table.AddColumn(Type, "Pad1", each Text.PadStart(Text.From([Column1], "en-GB"), 8, "0"), type text),
    Pad2 = Table.AddColumn(Pad1, "Pad2", each Text.PadStart(Text.From([Column2], "en-GB"), 4, "0"), type text),
    Pad3 = Table.AddColumn(Pad2, "Pad3", each Text.PadStart(Text.From([Column3], "en-GB"), 2, "0"), type text),
    #"Merged Columns" = Table.CombineColumns(Pad3,{"Pad1", "Pad2", "Pad3"},Combiner.CombineTextByDelimiter("", QuoteStyle.None),"Merged")
in
    #"Merged Columns"

Also if you not sure of how to write a function try Add Column From Examples. This has a go at guessing what your want and writes the functions for you.
