Is 43457 a prime number? What are the divisors of 43457?

## Is 43457 a prime number?

Yes, 43457 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 43457, the only two divisors are 1 and 43457. Therefore 43457 is a prime number.

As a consequence, 43457 is only a multiple of 1 and 43457.

Since 43457 is a prime number, 43457 is also a deficient number, that is to say 43457 is a natural integer that is strictly larger than the sum of its proper divisors, i.e., the divisors of 43457 without 43457 itself (that is 1, by definition!).

## Parity of 43457

43457 is an odd number, because it is not evenly divisible by 2.

## Is 43457 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 43457 is about 208.463.

Thus, the square root of 43457 is not an integer, and therefore 43457 is not a square number.

Anyway, 43457 is a prime number, and a prime number cannot be a perfect square.

## What is the square number of 43457?
