a) 140 chia hết cho x => x thuộc Ư(140)
168 chia hết cho x => x thuộc Ư(168)
Vậy x thuộc ƯC(140,168)
140 = 22.5.7
168 = 23.3.7
ƯCLN(140,168)=22.7 = 28
ƯC(140,168)=Ư(28) = {1;2;4;7;14;28}
Vì x>16 => x=28
b)x chia hết cho 24 => x thuộc B(24)
x chia hết cho 50 => x thuộc B(50)
x chia hết cho 60 => x thuộc B(60)
24 = 23.3
50 = 2.52
60 = 22.3.5
BCNN(24,50,60) = 23.3.52=600
BC(24,50,60) = B(600) = {0;600;1200;1800;2400;...}
Vì 0<x<600 => x thuộc rỗng(mình nghĩ câu này đề sai)
Học tốt!!!!!
