Is 22189 a prime number? What are the divisors of 22189?

## Is 22189 a prime number?

Yes, 22189 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 22189, the only two divisors are 1 and 22189. Therefore 22189 is a prime number.

As a consequence, 22189 is only a multiple of 1 and 22189.

Since 22189 is a prime number, 22189 is also a deficient number, that is to say 22189 is a natural integer that is strictly larger than the sum of its proper divisors, i.e., the divisors of 22189 without 22189 itself (that is 1, by definition!).

## Parity of 22189

22189 is an odd number, because it is not evenly divisible by 2.

## Is 22189 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 22189 is about 148.960.

Thus, the square root of 22189 is not an integer, and therefore 22189 is not a square number.

Anyway, 22189 is a prime number, and a prime number cannot be a perfect square.

## What is the square number of 22189?

The square of a number (here 22189) is the result of the product of this number (22189) by itself (i.e., 22189 × 22189); the square of 22189 is sometimes called "raising 22189 to the power 2", or "22189 squared".

The square of 22189 is 492 351 721 because 22189 × 22189 = 221892 = 492 351 721.

As a consequence, 22189 is the square root of 492 351 721.
