Is 41809 a prime number? What are the divisors of 41809?

## Is 41809 a prime number?

Yes, 41809 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 41809, the only two divisors are 1 and 41809. Therefore 41809 is a prime number.

As a consequence, 41809 is only a multiple of 1 and 41809.

Since 41809 is a prime number, 41809 is also a deficient number, that is to say 41809 is a natural integer that is strictly larger than the sum of its proper divisors, i.e., the divisors of 41809 without 41809 itself (that is 1, by definition!).

## Parity of 41809

41809 is an odd number, because it is not evenly divisible by 2.

## Is 41809 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 41809 is about 204.472.

Thus, the square root of 41809 is not an integer, and therefore 41809 is not a square number.

Anyway, 41809 is a prime number, and a prime number cannot be a perfect square.

## What is the square number of 41809?
