    We applied Euclid Division algorithm on n and 3.
    a = bq +r  on putting a = n and b = 3
    n = 3q +r  , 0<r<3
    i.e n = 3q   -------- (1),
    n = 3q +1 --------- (2),
    n = 3q +2  -----------(3)
    n = 3q is divisible by 3
    or n +2  = 3q +1+2 = 3q +3 also divisible by 3
    or n +4 = 3q + 2 +4 = 3q + 6 is also divisible by 3
    Hence n, n+2 , n+4 are divisible by 3.
