Question

is 91 a prime number​

Answer 1

Answer:

To be 91 a prime number, it would have been required that 91 has only two divisors, i.e., itself and 1. However, 91 is a semiprime (also called biprime or 2-almost-prime), because it is the product of a two non-necessarily distinct prime numbers. Indeed, 91 = 7 x 13, where 7 and 13 are both prime numbers.
