input: Write a function to find the three largest numbers in a list using the sorted function.
  assert find_largest_three([1, 6, 3, 8, 7, 4]) == [6, 7, 8]
  assert find_largest_three([10, 5, 3, 12, 7]) == [7, 10, 12]
  assert find_largest_three([20, 30, 10, 50, 40]) == [30, 40, 50]
output: def find_largest_three(numbers):
      return sorted(numbers)[-3:]
