Get a page ancestor from a most viewed list

get_ancestors will return array form value. So if you talking about how to get and display that ancestors with link:

<?php 
 $arrAncestors = get_ancestors( $post->ID, 'page'); 
 $cntAncestors = COUNT($arrAncestors);
 if($cntAncestors > 0) {
   $parentPostId = $arrAncestors[$cntAncestors - 1];
   $parentPageLink = get_permalink($parentPostId);
   $parentTitle = get_the_title($parentPostId);
   print '<li><a href="https://wordpress.stackexchange.com/questions/243836/<?php $parentPageLink ?>" title="<?php $parentTitle; ?>"><?php $parentTitle; ?></a></li>';
 }
?>

Hope you get solution from above snippet.
