## Is 49919 a prime number?

Yes, 49919 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 49919, the only two divisors are 1 and 49919. Therefore 49919 is a prime number.

As a consequence, 49919 is only a multiple of 1 and 49919.

Since 49919 is a prime number, 49919 is also a deficient number, that is to say 49919 is a natural integer that is strictly larger than the sum of its proper divisors, i.e., the divisors of 49919 without 49919 itself (that is 1, by definition!).

## Parity of 49919

49919 is an odd number, because it is not evenly divisible by 2.

## Is 49919 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 49919 is about 223.426.

Thus, the square root of 49919 is not an integer, and therefore 49919 is not a square number.

Anyway, 49919 is a prime number, and a prime number cannot be a perfect square.

## What is the square number of 49919?
