Answer:
k=64
Step-by-step explanation:
To find out the greatest integer such that 2^{k}is a factor if 67!
We divide the quotients by 2 and then finally add all the quotients.
67/2 = 33.5 --------> 33
33/2 = 16.5 ---------> 16
16/2 = 8 --------> 8
8/2= 4 ---------> 4
4/2 = 2--------> 2
2/2 = 1 ----------> 1
k= 33+16+8+4+2+1
= 64
Hence, 64 is the greatest integer such that 2^{k} is a factor of 67!.
