All listed words share the final sound sequence /æst/; -cast words add /k/ before it. Cast, forecast, and podcast are exact spelling-and-sound matches: they end in -cast and are pronounced /kæst/, just like the final syllable of broadcast /ˈbɹɑdkæst/. Last, fast, and past also share the /æst/ ending but use the spelling -ast. Be careful with lookalikes like breakfast /ˈbrɛkfəst/: although it starts with br- and ends with -st, its final syllable is /fəst/ with a schwa, so it does not match.
