Is 15959 a prime number?

Yes, 15959 is a prime number.

Indeed, the definition of a prime numbers is to have only two distinct positive divisors, 1 and itself. A number is a divisor of another number when the remainder of Euclid’s division of the second one by the first one is zero. Concerning the number 15959, the only two divisors are 1 and 15959. Therefore 15959 is a prime number.

As a consequence, 15959 is only a multiple of 1 and 15959.

Since 15959 is a prime number, 15959 is also a deficient number, that is to say 15959 is a natural integer that is strictly larger than the sum of its proper divisors, i.e., the divisors of 15959 without 15959 itself (that is 1, by definition!).
