Question

ƯCLN(33,55)

ƯCLN(48,90)

ƯCLN(105,210)

ƯCLN(48,60,120)

ƯCLN(45,60)

 

 

Answer 1

ƯCLN(33,55)=11

ƯCLN(48,90)=6

ƯCLN(105,210)=105

ƯCLN(48,60,120)=12

ƯCLN(45,60)=15

 

Answer 2

\(ƯCLN(33,55)\) 

\(33 = 3.11\)

\(55 = 5.11\)

\(ƯCLN(33,55) = 11\)

\(ƯCLN(105,210)\)

\(105 = 5.3.7\)

\(210 = 2.5.3.7\)

\(ƯCLN(105,210) = 5.3.7 = 105\)

\(ƯCLN(48,90)\)

\(48 = 2^4.3\)

\(90 = 2.5.3^2\)

\(ƯCLN(48,90) = 3.2 = 6\)

\(ƯCLN(48,60,120)\)

\(48 = 2^4.3\)

\(60 = 2^2.3.5\)

\(120 = 2^3.3.5\)

\(ƯCLN(48,60,120) = 2^2.3 = 4.3 = 12\)

\(ƯCLN(45,60)\)

\(45 = 3^2.5\)

\(60 = 2^2.3.5\)

\(ƯCLN(45,60) = 3.5 = 15\)
