Question

Is 121 prime or composite or neighter?

Answer 1

it is a composite no.

Answer 2

To be 121 a prime number, it would have been required that 121 has only two divisors, i.e., itself and 1. However, 121 is a semiprime (also called biprime or 2-almost-prime), because it is the product of a two non-necessarily distinct prime numbers. Indeed, 121 = 11 x 11, where 11 is a prime number.
