You can do something that I picked up from a answer from the WordPress StackExchange itself:

// determine the topmost parent of a term
function get_term_top_most_parent($term_id, $taxonomy){
    // começa do atual
    $parent  = get_term_by( 'id', $term_id, $taxonomy);
    // subir a árvore até encontrar um termo com parent = '0'
    while ($parent->parent != '0'){
        $term_id = $parent->parent;

        $parent  = get_term_by( 'id', $term_id, $taxonomy);
    }
    return $parent;
}
