Is 15959 a prime number? What are the divisors of 15959?

## 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!).

## Parity of 15959

15959 is an odd number, because it is not evenly divisible by 2.

## Is 15959 a perfect square number?

A number is a perfect square (or a square number) if its square root is an integer; that is to say, it is the product of an integer with itself. Here, the square root of 15959 is about 126.329.

Thus, the square root of 15959 is not an integer, and therefore 15959 is not a square number.

Anyway, 15959 is a prime number, and a prime number cannot be a perfect square.

## What is the square number of 15959?
