Question

Cho a = 45; b = 204 ; c = 126 Tìm ƯCLN a,b,c và BCNN a,b,c

Answer 1

Ta có: 45=3^2.5

          204=2^2.3.17

          126=2.2^3.7

=>ƯCLN(a,b,c)=3

    ƯCNN(a,b,c)=2^2.3^2.5.7.17=21420

Tick mình nha ^^

Answer 2

\(ƯCLN\left(a,b,c\right)=1\)

\(BCNN\left(a,b,c\right)=192780\)

Answer 3

\(ƯCLN\left(45;204;126\right)=3\)

\(BCNN\left(45;204;126\right)=21420\)
