ta có:
80=\(2^4\).5
126=2.\(3^2\).7
ƯCLN(80,126)=2
\(80=2^4\cdot5\)
\(126=2\cdot3^2\cdot7\)
ƯCLN(80,126) = 2
80=24x5x1
126=2x32x7x1
=>ƯCLN=2x1=2
Tìm UCLN( 80 ; 126 )
80 = 24 . 5 ; 126 = 2 . 32 . 7
Suy ra UCLN( 80 ; 126 ) = 2
80= 24 .5
126=2. 32 .7
ƯCLN (80,126)=24 .32.5.7=5040
Ta có: 80=24.5
126=2.33.7
=>ƯCLN(80;126)=2
Học tốt nha bạn!!
