Is 22447 a prime number? What are the divisors of 22447?

## Is 22447 a prime number?

Yes, 22447 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 22447, the only two divisors are 1 and 22447. Therefore 22447 is a prime number.

As a consequence, 22447 is only a multiple of 1 and 22447.

Since 22447 is a prime number, 22447 is also a deficient number, that is to say 22447 is a natural integer that is strictly larger than the sum of its proper divisors, i.e., the divisors of 22447 without 22447 itself (that is 1, by definition!).

## Parity of 22447

22447 is an odd number, because it is not evenly divisible by 2.

## Is 22447 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 22447 is about 149.823.

Thus, the square root of 22447 is not an integer, and therefore 22447 is not a square number.

Anyway, 22447 is a prime number, and a prime number cannot be a perfect square.

## What is the square number of 22447?
