My brother Alex is a footballer and he is very fit. He usually (1)sleeps eight hours and doesn’t go to bed late . He does morning(2) exercises regularly and runs 10 km every day. Alex (3) doesn't like watching TV or playing computer games. He thinks it’s (4) better to ride a bike or walk in the park . Last year my brother (5) kept to a very strict diet of vegetables, water and fish before an important match. I hope Alex (6) make a very successful career in football because he is a real sportsman. sleep
210 : 2 = 105 910 : 2 = 455
105 : 3 = 35 455 : 5 = 91
35 : 5 = 7 91 : 7 = 13
7 : 7 = 1 13 : 13 = 1
210 = 2 * 3 * 5 * 7 910 = 2 * 5 * 7 * 13
НОК (210 и 910) = 2 * 3 * 5 * 7 * 13 = 2 730 - наименьшее общее кратное
