function leastFactor(n) {

if (n==0) return 0;
if (n%1 || nn<2) return 1;
if (n%2==0) return 2;
if (n%3==0) return 3;
if (n%5==0) return 5;
var m = Math.sqrt(n);
for (var i=7;i<=m;i+=30) {
if (n%i==0) return i;
if (n%(i+4)==0) return i+4;
if (n%(i+6)==0) return i+6;
if (n%(i+10)==0) return i+10;
if (n%(i+12)==0) return i+12;
if (n%(i+16)==0) return i+16;
if (n%(i+22)==0) return i+22;
if (n%(i+24)==0) return i+24;
}
return n;
}
var p = pvalue;
var s = svalue;
var y = yvalue;
eval(Pcalc);
var n = leastFactor(p);
var RNKEY1 = "RNKEY=" + n + "" + p/n + ":" + s + y;
