title: Obtain common values between 5 from the same column of different dataframes
body: <p>I am struggling to extract the common values between a specific column of 5 different dataframes. I know how to do this with two, but not with more.</p>
  
  <pre><code>df1$ID&lt;-c(121, 122, 176)
  df2$ID&lt;-c(121, 88, 199)
  df3$ID&lt;-c(77, 121, 230)
  df4$ID&lt;-c(6, 88, 121)
  df5$ID&lt;-c(121, 122, 123)
  
  </code></pre>
  
  <p>In this example, my desired output would be:</p>
  
  <pre><code>result&lt;-c(121)
  
  </code></pre>
  
  <p>Thanks!</p>
