Anyway, see if you can find my flag. Hint: This is just math. You're probably not going to find any sort of specialized attack.

fun fact: i hate how this level is even EASIER than RSA beginner and RSA noob combined. (this one uses e=65537 (default) as a part of the RSA encryption dude! come on, no way this is hard difficulty! even RSA noob is harder than this one to figure out! that certain french website is all you need? like come on man...

So many "cool" people here. Yes, it's easy with tools, but is it easy just doing straight up math? Maybe, maybe not, since it depends on the person's level of mathematical skills, but other than to people who are good at math, I doubt it can be seen as "easy," so get off your high horses.
