# Is 949 a prime number?

It is possible to find out using mathematical methods whether a given integer is a prime number or not.

For 949, the answer is: No, 949 is not a prime number.

The list of all positive divisors (i.e., the list of all integers that divide 949) is as follows: 1, 13, 73, 949.

For 949 to be a prime number, it would have been required that 949 has only two divisors, i.e., itself and 1.

As a consequence:

For 949 to be a prime number, it would have been required that 949 has only two divisors, i.e., itself and 1.

However, 949 is a **semiprime** (also called biprime or 2-almost-prime), because it is the product of a two non-necessarily distinct prime numbers. Indeed, 949 = 13 x 73, where 13 and 73 are both prime numbers.

### Is 949 a deficient number?

Yes, 949 is a deficient number, that is to say 949 is a natural number that is strictly larger than the sum of its proper divisors, i.e., the divisors of 949 without 949 itself (that is 1 + 13 + 73 = 87).
