Question

ƯCLN(104;130). 

BCNN(104;130)

 

Answer 1

Ta có: \(104=2^3.13\); \(130=2.5.13\)

\(\Rightarrow\) ƯCLN(104, 130) = \(2.13=26\); 

BCNN(104, 130) = \(2^3.5.13=520\)

Answer 2

Ta có: $104={}^{}.13$; $130=\mathrm{2.5.13}$

$\Rightarrow$ ƯCLN(104, 130) = $2.13=26$; 

BCNN(104, 130) = ${}^{}.5.13=520$
