    Answer: (4) 1653
    Explanation:-
    Formula-
    The sum of the natural numbers = n (n + 1)/2
    Where, n – number of the natural numbers.

    Then, the sum of first 57 natural number = 57 (57 + 1)/2
    = 57 x 58/2
    = 57 x 29
    =  1653
    Then, the sum of first 57 natural numbers is 1653.
    Hence, the answer is (4) 1653.
