It can be seen that the number, 125874, and its double, 251748, contain exactly the same digits, but in a different order.
Find the smallest positive integer, x, such that 2x, 3x, 4x, 5x, and 6x, contain the same digits.
function lowestPermutedMultiple(n) {
let base = n;
let numDigits = n.toString().length;
let i = 1;
let solution = i;
while ((n * i).toString().length <= numDigits) {
if (base.toString().split('').sort().join('') == (n*i).toString().split('').sort().join('')) {
solution = i;
}
i++;
}
return solution;
}describe("Solution", function(){
it("should work", function(){
let n = 125874;
let solution = 2;
Test.assertEquals(lowestPermutedMultiple(n), solution);
});
});
