At the age they were building pyramids and would have supposedly recarved the Sphinx, they were mostly using very large stone blocks. They only switched to smaller stone blocks in the Amarna period when Akhenaten had them do it to speed up construction. But that was centuries later.
You can chop it into smaller blocks to use on something nearby, idk honestly but I’d just assume it’s easier than bringing a new block from quarry
