Ответ:

252

Пошаговое объяснение:

1) Сначала каждое число надо разложить на простые множители:

28 | 2

14  | 2

 7 | 7

 1

Значит, 28 = 2 · 2 · 7

63 | 3

21  | 3

 7  | 7

 1

Значит,  63 = 3 · 3 · 7

2) Затем надо составить произведение из неповторяющихся множителей:

НОК (28 и 63) = 2 · 2 · 7 · 3 · 3 = 252

Вторую семёрку не включаем, так как она повторяется.

Ответ:  НОК (28; 63) = 252

Примечание:

Сами для себя делаем проверку - чтобы при делении получалось целое число:

252 : 28 = 9

252 : 63 = 4

Перевод текста
According to some people, it is better to work abroad. Others say that they would prefer working in their own country.
As nowadays travelling has become cheaper and easier, more and more people have the chance to work in a foreign country. Millions of people are now working overseas. However, others are convinced that it is better to work in your own country.
On the one hand, working in a foreign country gives you a wider view of the world. To my mind, it gives you an opportunity to work on some international projects, to make friends with people of different nationalities, to learn more about foreign culture, to gain useful knowledge and experience and to learn foreign languages.
On the other hand, a lot of people say that it is rather bad when experienced specialists leave their motherland in order to work abroad. Our country needs good doctors, scientists, inventors, sportsmen, writers and so on. What is more, working abroad has a number of disadvantages. Firstly, it is rather difficult to get a work permit. Secondly, settling in can also be a problem. Thirdly, a lot of people say they find having to speak a foreign language 24 hours rather exhausting. But despite the challenges, many people find working abroad extremely interesting.
To conclude, I think that working in a foreign country can help you improve your knowledge, broaden your mind and make a career. If you give yourself time to settle in and discover new things, you will be able to realize your potential and to succeed. Anyway, you can always return to your mother country and work to improve its economy, politics or culture.
