Smallest Multiple

Problem 5.js

var iterator = 1;

var isMultiple = function(number) {
    // divide the number by every number between 1 & 20
    for(var i = 1; i <= 20; i++)
    {
        if(number % i != 0)
        {
            // If the number wasn't divisible then we know it can't be a correct answer
            return false;
        }
    }
    
    return true;
}

// Test numbers until a valid value is found
while(!isMultiple(iterator))
{
    iterator++;
}

console.log(iterator + " is the smallest multiple");
