The first or the second time? (Or this third time, where you broke the quotation?)
I'll include my thoughts about the second time in bold:
"the LCM of 5 and 7 (that's 35, but go on) which is higher than 36 (no it's not, 35 is lower than 36) would stand out to be 70 (what does"stand out to be" mean? This might be my fault for not knowing that expression, but I do claim it's at least unusual) which the LCM of 70 and 36 is (70 is the LCM of 70 and 36???) 1260 (how does that dangling number fit into the sentence??)."
The (correct) lack of a comma before "which is higher than 36" could have given me a hint, but the overall lack of commas and sentence structure didn't make me think about that.
Admittedly this one was rather ok and after some thinking I'm able to understand what you meant (I still think it's not a proper sentence), but the first one I really couldn't.
Always trying to please. And I'm particularly happy I could use that Antoine Dodson meme again ("windows" is the same and "disks"/"drive" are so close to "kids"/"wife", it's uncanny how well it fits. And "husband" and "stick" are at least somewhat related, if you know what I mean).
