Câu 1:
uses crt;
var m,n,ucln,i:integer;
begin
clrscr;
write('Nhap m='); readln(m);
write('Nhap n='); readln(n);
ucln:=1;
if m<n then
begin
for i:=1 to m do
if (m mod i=0) and (n mod i=0) then
begin
if ucln<i then ucln:=i;
end;
end
else begin
for i:=1 to n do
if (m mod i=0) and (n mod i=0) then
begin
if ucln<i then ucln:=i;
end;
end;
writeln(ucln);
readln;
end.

Mình xin sửa lại một chút:
uses crt;
const fi='kiemtra.txt';
var f1:text;
a:array[1..100]of integer;
min,n,i:integer;
{----------------chuong-trinh-con-------------------}
function nn(x,y:integer):integer;
begin
if x<y then nn:=x
else nn:=y;
end;
{-----------------chuong-trinh-chinh-----------------}
begin
clrscr;
assign(f1,fi); reset(f1);
readln(f1,n);
for i:=1 to n do
read(f1,a[i]);
min:=nn(a[1],a[2]);
for i:=3 to n do
if min>a[i] then min:=a[i];
writeln(min);
readln;
end.
Bài 1:
function min(a,b:longint):longint;
begin
min:=a;
if min>b then min:=b;
end;
Bài 2:
function canhhuyen(a,b:real):real;
var c:real;
begin
c:=sqrt(sqr(a)+sqr(b));
canhhuyen:=c;
end;
uses crt;
var a,b,bcnn:integer;
{----------------------chuong-trinh-con----------------------------}
function ucln(var n,m:integer):integer;
var i:integer;
begin
ucln:=1;
for i:=1 to n*m do
if (n mod i=0) and (m mod i=0) then
begin
if ucln<i then ucln:=i;
end;
end;
{---------------------chuong-trinh-chinh--------------------------}
begin
clrscr;
write('Nhap a='); readln(a);
write('Nhap b='); readln(b);
bcnn:=a*b div ucln(a,b);
writeln('Boi chung nho nhat=',bcnn);
readln;
end.
uses crt;
var a,b,c,nn:integer;
//chuongtrinhcon
function min(var x,y:integer):integer;
begin
if x<y then min:=x
else min:=y;
end;
//chuongtrinhchinh
begin
clrscr;
readln(a,b,c);
nn=min(a,b);
nn=min(nn,c);
writeln(nn);
readln;
end.
int BCNN(int a, int b)
{
int result = UCLN(a, b);
return a * b / result;
}
int main()
{
int a, b; cout << "a = ";
cin >> a;
cout << "b = ";
cin >> b;
int result = UCLN(a, b);
cout << "UCLN : "<<result; cout << "\n";
result = BCNN(a, b);

Biết viết mỗi C++, Pascal thì miss gần hết :(
uses crt;
var a,b,bcnn,i:longint;
begin
clrscr;
write('Nhap a='); readln(a);
write('Nhap b='); readln(b);
bcnn:=a*b;
for i:=a*b-1 downto 1 do
if (i mod a=0) and (i mod b=0) then
begin
if bcnn>i then bcnn:=i;
end;
writeln('Boi chung nho nhat la: ',bcnn);
readln;
end.
