If n is an integer and n=2.3.5.7.11.13/77k then which of the following could be the value of k?
(A) 22
(B) 26
(C) 35
(D) 54
(E) 60

n=2.3.5.7.11.13/77k
n=2.3.5.13/k

For N to be an integer, K would have to have (2.3.5.13) as its prime factors OR ALL the prime factors of K would have to be from this list (2.3.5.13). Only 26 (13.2) works out.

Hence (B)
