javascript - Smallest Common Multiple Code produces the wrong answer on one array -

[edit]

i should clarify, attempting find smallest common multiple of range of numbers. sorry that. have attempted solution still run incorrect answer on last array [23, 18].

function smallestcommons(arr) {   arr = arr.sort(function (a, b) {  return - b;  });    var count = 1;    (var = arr[0]; <= arr[1]; i++) {     if (count % !== 0) {       = arr[0];       count++;     }    }    return count; }   smallestcommons([23,18]); 

my solution produces 2018940 when should 6056820

your endless loop becouse of inner loop starts @ value 19 , runs 22

414 (smallestmultiple of 18 & 23) % 19 == 15 414 % 20 = 14 414 % 21 = 15 414 % 22 = 18 

which leads statement if(count % == 0) being false , loop goes on 415 416 ...

if u want least common multiple

var issmallestmultipe = 0; while(issmallestmultiple == 0) {    for(var = 1; <= arr[1]; i+)    {       if((arr[0]*i) % arr[1] == 0)       {          issmallestmultiple = arr[0] * i;                  }    } }
