Is 11443 a prime number? What are the divisors of 11443?

## Is 11443 a prime number?

Yes, 11443 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 11443, the only two divisors are 1 and 11443. Therefore 11443 is a prime number.

As a consequence, 11443 is only a multiple of 1 and 11443.

Since 11443 is a prime number, 11443 is also a deficient number, that is to say 11443 is a natural integer that is strictly larger than the sum of its proper divisors, i.e., the divisors of 11443 without 11443 itself (that is 1, by definition!).

## Parity of 11443

11443 is an odd number, because it is not evenly divisible by 2.

## Is 11443 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 11443 is about 106.972.

Thus, the square root of 11443 is not an integer, and therefore 11443 is not a square number.

Anyway, 11443 is a prime number, and a prime number cannot be a perfect square.

## What is the square number of 11443?

The square of a number (here 11443) is the result of the product of this number (11443) by itself (i.e., 11443 × 11443); the square of 11443 is sometimes called "raising 11443 to the power 2", or "11443 squared".

The square of 11443 is 130 942 249 because 11443 × 11443 = 114432 = 130 942 249.

As a consequence, 11443 is the square root of 130 942 249.
