Is 94 a prime number?
It is possible to find out using mathematical methods whether a given integer is a prime number or not.
For 94, the answer is: No, 94 is not a prime number.
The list of all positive divisors (i.e., the list of all integers that divide 94) is as follows: 1, 2, 47, 94.
For 94 to be a prime number, it would have been required that 94 has only two divisors, i.e., itself and 1.

As a consequence:
For 94 to be a prime number, it would have been required that 94 has only two divisors, i.e., itself and 1.
However, 94 is a semiprime (also called biprime or 2-almost-prime), because it is the product of a two non-necessarily distinct prime numbers. Indeed, 94 = 2 x 47, where 2 and 47 are both prime numbers.
Is 94 a deficient number?
Yes, 94 is a deficient number, that is to say 94 is a natural number that is strictly larger than the sum of its proper divisors, i.e., the divisors of 94 without 94 itself (that is 1 + 2 + 47 = 50).
