Is 11969 a prime number? What are the divisors of 11969?

## Is 11969 a prime number?

Yes, 11969 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 11969, the only two divisors are 1 and 11969. Therefore 11969 is a prime number.

As a consequence, 11969 is only a multiple of 1 and 11969.

Since 11969 is a prime number, 11969 is also a deficient number, that is to say 11969 is a natural integer that is strictly larger than the sum of its proper divisors, i.e., the divisors of 11969 without 11969 itself (that is 1, by definition!).

## Parity of 11969

11969 is an odd number, because it is not evenly divisible by 2.

## Is 11969 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 11969 is about 109.403.

Thus, the square root of 11969 is not an integer, and therefore 11969 is not a square number.

Anyway, 11969 is a prime number, and a prime number cannot be a perfect square.

## What is the square number of 11969?
