## Is 47819 a prime number?

Yes, 47819 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 47819, the only two divisors are 1 and 47819. Therefore 47819 is a prime number.

As a consequence, 47819 is only a multiple of 1 and 47819.

Since 47819 is a prime number, 47819 is also a deficient number, that is to say 47819 is a natural integer that is strictly larger than the sum of its proper divisors, i.e., the divisors of 47819 without 47819 itself (that is 1, by definition!).

## Parity of 47819

47819 is an odd number, because it is not evenly divisible by 2.

## Is 47819 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 47819 is about 218.676.

Thus, the square root of 47819 is not an integer, and therefore 47819 is not a square number.

Anyway, 47819 is a prime number, and a prime number cannot be a perfect square.

## What is the square number of 47819?
