input: Write a python function to find the most common element in a list using the Counter class from the collections module.
  assert find_most_common([2, 3, 4, 5, 2, 3, 2, 5, 6, 7]) == 2
  assert find_most_common([10, 20, 10, 30, 30, 30, 40, 50]) == 30
  assert find_most_common([1, 1, 2, 2, 3, 3, 3]) == 3
output: from collections import Counter
  
  def find_most_common(lst):
      counter = Counter(lst)
      most_common_element = counter.most_common(1)[0][0]
      return most_common_element
