## Is 49639 a prime number?

Yes, 49639 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 49639, the only two divisors are 1 and 49639. Therefore 49639 is a prime number.

As a consequence, 49639 is only a multiple of 1 and 49639.

Since 49639 is a prime number, 49639 is also a deficient number, that is to say 49639 is a natural integer that is strictly larger than the sum of its proper divisors, i.e., the divisors of 49639 without 49639 itself (that is 1, by definition!).

## Parity of 49639

49639 is an odd number, because it is not evenly divisible by 2.

## Is 49639 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 49639 is about 222.798.

Thus, the square root of 49639 is not an integer, and therefore 49639 is not a square number.

Anyway, 49639 is a prime number, and a prime number cannot be a perfect square.

## What is the square number of 49639?
