Is 5443 a prime number? What are the divisors of 5443?

## Is 5443 a prime number?

Yes, 5443 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 5443, the only two divisors are 1 and 5443. Therefore 5443 is a prime number.

As a consequence, 5443 is only a multiple of 1 and 5443.

Since 5443 is a prime number, 5443 is also a deficient number, that is to say 5443 is a natural integer that is strictly larger than the sum of its proper divisors, i.e., the divisors of 5443 without 5443 itself (that is 1, by definition!).

## Parity of 5443

5443 is an odd number, because it is not evenly divisible by 2.

## Is 5443 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 5443 is about 73.777.

Thus, the square root of 5443 is not an integer, and therefore 5443 is not a square number.

Anyway, 5443 is a prime number, and a prime number cannot be a perfect square.

## What is the square number of 5443?

The square of a number (here 5443) is the result of the product of this number (5443) by itself (i.e., 5443 × 5443); the square of 5443 is sometimes called "raising 5443 to the power 2", or "5443 squared".

The square of 5443 is 29 626 249 because 5443 × 5443 = 54432 = 29 626 249.

As a consequence, 5443 is the square root of 29 626 249.

## Number of digits of 5443
