Answer 1

Эти числа делятся только на 20

Answer 2

Um, it seems like you provided a sequence of numbers: 420, 140, and 180. However, it's not clear what you are asking for. The term "НОК" (NOK) is the Russian acronym for "наименьшее общее кратное," which translates to "least common multiple" or "LCM" in English. If that's what you are referring to, then the LCM of these three numbers can be calculated as follows:

LCM(420, 140, 180) = 1260

So, the least common multiple of 420, 140, and 180 is 1260. If you meant something else or have any other questions, please feel free to clarify, and I'll be glad to assist you further.
