(1) x is a factor of 91: 91 = 7*13. So, x can be 7, 13 or 91. Not sufficient.

(2) x is a factor of 104: 104 = 2^3*13. x may or may not be 13. Not sufficient.

(1)+(2) 91 = 7*13 and 104 = 2^3*13 have only 2 factors in common 1 and 3. Since we are given that x is greater than 1, then x = 13. Sufficient.
