I haven't checked whether your code fails or passes, but you are definitely getting a bunch of warnings (which are not errors, though they appear in stderr in the output). Write your code in a proper IDE with linting support (e.g. VS Code + RustAnalyzer) to see all the slightly silly thing's your code is doing.

I just solved this and there are not errors in sample or submission tests.

Rust random-test failing but anyways resulting as a correct solution.

It's normal to see such a big result because you need to find the least common multiple of several elements. For example, the least common multiple of 11, 13, 15 and 17 is 11 * 13 * 15 * 17 = 36465. Maybe it could help to (re-)read about what a least common multiple is. :)

As i am getting really big test results for instance
34 should equal 5290740 i was wondering if this was a kata issue or not, since i don't think it's possible to get 5290740 as least multiple without a big input too.

probably i didnt understood the challenge as i should, so i wanted to ask this before retrying

I don't understand why am getting a format-specifier expection feedback in C
All the previous tests works fine, this is confusing me quite a lot.
Could it be an issue with my code or the actual kata?

Here's my output as my passed result:

elbuod
s% .) d%( LLdecaps
s% .)d %( LLIsdro w
