Multiple 404

This directory website that I made singaporelandscaping.com has been up for a while, it’s a side project I’m doing to learn code. But in my Google search console I kept seeing pages that do not exist on my site being crawled and labeled as 404.
Any ideas how to resolve this issue? Chatgpt says to noindex the URLs but I didn’t even know it was created in the first place

Hi @sglandscapes,

Can you share some 404 URL examples?

like I would get /product/21 instead of product/flower-pot as an example
