we can split 6^m to 2^m x 3^m
that means we need to >= number of 2's and equal number of 3's in the numerator than the denominator in order for the faction to be an integer
In this Q, you can do a quick divisibilty test and find out how many 3's are there, since 3's are rare in the sequence, we don't have to worry about number of 2's.
we have 5 3's so answer should be 5

I also thought about it for a while until I was like dhu!
The N and K is used for the numerator - n&k = n * (n=1).... *(k)
Makes sense now? The numerator is in the form of n&k NOT n*k ( where n and k are integers

mathematical solving of this ques is easy...
its 5
logically we have to get numbers which have factors as 2& 3
and 6 there will be 5 so M=5
