title: How do I find the lowest common multiple of two numbers?
body: <p>I know this is a classic interview question, but here is my quick attempt at creating a function which returns the lowest common multiple of two numbers, something I never have to do in my day job:</p>
  
  <pre><code>def calc_common_multiplyer(int_low, int_high)
    i = 1
    int_high_res = []
  
    while true
      int_high_res &lt;&lt; int_high * i
      if int_high_res.include?(int_low * i)
        return int_low * i
      end 
      i = i+1
    end
  end
  </code></pre>
  
  <p>I feel that this is very clunky. Is there a more efficient or standard solution?</p>
