Is 11923 a prime number? What are the divisors of 11923?

## Is 11923 a prime number?

Yes, 11923 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 11923, the only two divisors are 1 and 11923. Therefore 11923 is a prime number.

As a consequence, 11923 is only a multiple of 1 and 11923.

Since 11923 is a prime number, 11923 is also a deficient number, that is to say 11923 is a natural integer that is strictly larger than the sum of its proper divisors, i.e., the divisors of 11923 without 11923 itself (that is 1, by definition!).

## Parity of 11923

11923 is an odd number, because it is not evenly divisible by 2.

## Is 11923 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 11923 is about 109.192.

Thus, the square root of 11923 is not an integer, and therefore 11923 is not a square number.

Anyway, 11923 is a prime number, and a prime number cannot be a perfect square.

## What is the square number of 11923?

The square of a number (here 11923) is the result of the product of this number (11923) by itself (i.e., 11923 × 11923); the square of 11923 is sometimes called "raising 11923 to the power 2", or "11923 squared".

The square of 11923 is 142 157 929 because 11923 × 11923 = 119232 = 142 157 929.

As a consequence, 11923 is the square root of 142 157 929.

## Number of digits of 11923
