Answer 2

Answer:

To be 169 a prime number, it would have been required that 169 has only two divisors, i.e., itself and 1. However, 169 is a semiprime (also called biprime or 2-almost-prime), because it is the product of a two non-necessarily distinct prime numbers. Indeed, 169 = 13 x 13, where 13 is a prime number.
