Is 25747 a prime number? What are the divisors of 25747?

## Is 25747 a prime number?

Yes, 25747 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 25747, the only two divisors are 1 and 25747. Therefore 25747 is a prime number.

As a consequence, 25747 is only a multiple of 1 and 25747.

Since 25747 is a prime number, 25747 is also a deficient number, that is to say 25747 is a natural integer that is strictly larger than the sum of its proper divisors, i.e., the divisors of 25747 without 25747 itself (that is 1, by definition!).

## Parity of 25747

25747 is an odd number, because it is not evenly divisible by 2.

## Is 25747 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 25747 is about 160.459.

Thus, the square root of 25747 is not an integer, and therefore 25747 is not a square number.

Anyway, 25747 is a prime number, and a prime number cannot be a perfect square.

## What is the square number of 25747?
