Is 22409 a prime number? What are the divisors of 22409?

Is 22409 a prime number?

Yes, 22409 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 22409, the only two divisors are 1 and 22409. Therefore 22409 is a prime number.

As a consequence, 22409 is only a multiple of 1 and 22409.

Since 22409 is a prime number, 22409 is also a deficient number, that is to say 22409 is a natural integer that is strictly larger than the sum of its proper divisors, i.e., the divisors of 22409 without 22409 itself (that is 1, by definition!).

Parity of 22409

22409 is an odd number, because it is not evenly divisible by 2.

Is 22409 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 22409 is about 149.696.

Thus, the square root of 22409 is not an integer, and therefore 22409 is not a square number.

Anyway, 22409 is a prime number, and a prime number cannot be a perfect square.

What is the square number of 22409?
