highest power of the 2 in the following series 1!+2!+3!---------------+600!
A.1
B.496
C.128
D.192

• highest power of 2 is zero
  because adding the series 2!+3!+.......+600! we get even number
  and when we add 1! to that even number we get odd number.

• every element in above series having at least one 2 as a factor..except first element....summation of above series will be odd so there is not any degree of 2 as factor of that summation..so.. power is 0

• @Pratik Mishra i understand what u are trying to imply but what is the answer which option to choose from the above then ????

• Here the 1st term 1! is an odd nos and each of the remaining terms from 2! , 3! to.....600! is even. So the overall sum will be odd and hence not divisible by 2. So the power of 2 will be 0
