Gọi số người tham gia buổi đồng diễn là a ( a \(\in\) N* )
Theo đề bài ta có
350 < a < 400
a \(⋮\) 5
a\(⋮\) 6
a\(⋮\) 8
\(\Rightarrow\) a \(\in\) BC ( 5 ; 6 ; 8 ) , 350 < a < 400
5 = 5
6 = 2 . 3
8 = 23
BCNN ( 5 ; 6 ; 8 ) = 5 . 23 . 3 = 120
a \(\in\) BC ( 5; 6 ; 8 ) = B ( 120 ) = { 0 ; 120 ; 240 ; 360 ; 480 ; 600 ...}
mà 350 < a < 400
\(\Rightarrow\) a \(\in\) { 360 }
Vậy số người tham gia buổi đồng diễn là 360 người
