How it's used

Mathematical terminology in Hong Kong schools is often taught using a mix of English and Cantonese, so students frequently refer to this concept simply as GCF. While the term is standard in formal education, you will rarely hear it used outside of a classroom or academic context. It is a precise technical noun that does not carry the metaphorical weight it sometimes does in other languages.
