if 300 ! / 10 ^ n is an integer , what is the largest possible value of n ?
"the question actually asks the highest power of 10 which divides 300 ! ( for a number to be an integer - without any remainder all the trailing zeroe ' s must be divided by the denominator ) 10 = 2 x 5 300 factorial will have 74 as - 300 / 5 = 60 60 / 5 = 12 12 / 5 = 2 so answer will be ( d ) 74"
add(divide(divide(300, add(const_4, const_1)), add(const_4, const_1)), divide(300, add(const_4, const_1)))
