Найдите наименьшее общее кратное (нок) чисел: а) 12 и 24 б) 30 и 90 в) 22 и 88 г) 80 и 640

А) 12 = 2 * 2 * 3
24 = 2 * 2 * 2 * 3
НОК (12; 24) = 2 * 2 * 2 * 3 = 24
б) 30 = 2 * 3 * 5
90 = 2 * 3 * 3 * 5
НОК (30; 90) = 2 * 3 * 3 * 5 = 90
в) 22 = 2 * 11
88 = 2 * 2 * 2 * 11
НОК (22; 88) = 2 * 2 * 2 * 11 = 88
г) 80 = 2 * 2 * 2 * 2 * 5
640 = 2 * 2 * 2 * 2 * 2 * 2 * 2 * 5 
НОК (80; 640) = 2 * 2 * 2 * 2 * 2 * 2 * 2 * 5  = 640

▪НОК(12; 24) = 2 × 2 × 2 × 3 = 24
12 = 2 × 2 × 3
24 = 2 × 2 × 2 × 3

▪НОК(30; 90) = 2 × 3 × 3 × 5 = 90
30 = 2 × 3 × 5
90 = 2 × 3 × 3 × 5

▪НОК(22; 88) = 2 × 2 × 2 × 11 = 88
22 = 2 × 11
88 = 2 × 2 × 2 × 11

▪НОК(80; 640) = 2 × 2 × 2 × 2 × 2 × 2 × 2 × 5 = 640
80 = 2 × 2 × 2 × 2 × 5
