# Is 703 a prime number?

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

For 703, the answer is: No, 703 is not a prime number.

The list of all positive divisors (i.e., the list of all integers that divide 703) is as follows: 1, 19, 37, 703.

For 703 to be a prime number, it would have been required that 703 has only two divisors, i.e., itself and 1.

As a consequence:

For 703 to be a prime number, it would have been required that 703 has only two divisors, i.e., itself and 1.

However, 703 is a **semiprime** (also called biprime or 2-almost-prime), because it is the product of a two non-necessarily distinct prime numbers. Indeed, 703 = 19 x 37, where 19 and 37 are both prime numbers.

### Is 703 a deficient number?

Yes, 703 is a deficient number, that is to say 703 is a natural number that is strictly larger than the sum of its proper divisors, i.e., the divisors of 703 without 703 itself (that is 1 + 19 + 37 = 57).
