Bài 1:

a) 22 ; 33 ; 55

Ta có:

22 = 2 . 11

33 = 3 . 11

55 = 5 . 11

⇒ BCNN(22 ; 33 ; 55) = 2 . 3 . 5 . 11 = 330

⇒ BC(22 ; 33 ; 55) = B(330) = { 0 ; 330 ; 660 ; 990 ; ... }

b) 126 ; 24 ; 38

Ta có:

126 = 2 . 3² . 7

24 = 2³ . 3

38 = 2 . 19

⇒ BCNN(126 ; 24 ; 38) = 2³ . 19 . 3² . 7 = 9576

⇒ BC(126 ; 24 ; 38) = B(9576) = { 0 ; 9576 ; 19152 ; ... }
