Нок(12;20)= 12=.......... 20=....... Нок(34;45)= 34......... 45= Нок(108;144)...

Question

Нок(12;20)=
12=.......... 20=.......
Нок(34;45)=
34......... 45=
Нок(108;144)
108......144=

Answer 1

НОК (12;20) = 2 * 2 * 3 * 5 = 60
12 = 2 * 2 * 3
20 = 2 * 2 * 5

НОК (34;45) = 2 * 3 * 3 * 5 * 17 = 1530
34 = 2 * 17
45 = 3 * 3 * 5

НОК (108;144) = 2 * 2 * 2 * 2 * 3 * 3 * 3 = 432
108 = 2 * 2 * 3 * 3 * 3
144 = 2 * 2 * 2 * 2 * 3 * 3

Answer 2

1530
108=2*2*3*3*3=2²*3³
144=2*2*2*2*3*3=2⁴*3²
НОК(108;144)=2⁴*3³=432
