Since n=2 x 3 x5 x7 x11 x 13/77k, n= (2*3*5*7*11*13)77k
n= 2*3*5*13*77/77k = 2*3*5*13/k
= 390/k.

Therefore, 390 must be divisible by k w/ no remainder to make k an integer.
The only answer choice that can divide 390 w/ no remainder is 26 or -26.
OA is B

ans: c

n = 2*3*5*7*11*13/7*11k = 2*3*5*13/k thus k could be (2,3,5,13)x, x is a positive intiger or any combination of the same.

b is definitely the answer
