Ta có:

Ta đặt giả sử 2 số đó là\(16a\)\(16b\)

\(16\cdot a\cdot b=192\Leftrightarrow ab=192:16\)

\(\Rightarrow ab=12\)

 \(a\cdot b=12\Rightarrow\hept{\begin{cases}a=1;b=12\\a=2;b=6\end{cases}}\Leftrightarrow\hept{\begin{cases}a=16;b=192\\a=32;b=96\end{cases}}\)\(BCNN\left(32,96\right)=96\Rightarrow\hept{\begin{cases}a=16\\b=192\end{cases}}\)

Nên hai số đó là 16 và 192

Ta có :

\(a=m.c\)

\(b=n.c\)

\(\Rightarrow\) \(ƯCLN\left(a,b\right)=c\)

\(BCNN\left(a,b\right)=c.m.n\)

Vì  \(ƯCLN\left(a,b\right)=16\Rightarrow a=16m\)

\(b=16n\)

Sao cho \(ƯCLN\left(m,n\right)=1\)

\(BCNN\left(a,b\right)=16.m.n\)

\(\Rightarrow\)\(240=16.m.n\)

\(\Rightarrow\)\(m.n=15\)

Vây \(\left(a,b\right)\)thỏa mãn :

\(\left(16;240\right);\left(240;16\right);\left(80;48\right);\left(48;80\right)\)

a) goi hai so la a ; b va a >b

vi UCLN(a,b)=18=>a=18k            ;       b=18q       (trong do UCLN (k,q)=1 va k>q)

=>a+b=162

18k+18q =162

18(k+q)=162

k+q=9

ta co bang sau
