Gọi 2 số cần tìm là a;b
(a;b) =d
a=dq;b=dp với(q;p)=1
BCNN(a;b)=ab/UCNN =ab/d
=>ab/d +d =23 => ab +d
2=23d=> ab=d(23-d)
vì (a;b)=d => ab chia hết cho d
2 =>23-d chia hết cho d => 23 chia hết cho d
d=1;23
+d=1=>BCNN(a;b)=23-1=22=21+1=19+2=17+5=...
+d=23...

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
