algorithm for factoring a number into two factors
var k,l,n,s,j,d,c,y,r,b:biginteger;
begin var x:=ReadString('введите число:').ToBigInteger; var a:=x div 2; repeat b:=a; a:=(a+x div a)div 2 until a>=b; s:=a; n:=x-sqr(s); k:=n div s; j:=n mod s; l:=s+k; d:= s-j; repeat s:=s-1; d:=d-1; r:=l-d; c:=r div s; y:=r mod s; l:=l+1+c; j:=y; d:=s-j; until j=0; writeln('l=',l); writeln ('s=',s); end. |
