Is 11897 a prime number? What are the divisors of 11897?

Is 11897 a prime number?

Yes, 11897 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 11897, the only two divisors are 1 and 11897. Therefore 11897 is a prime number.

As a consequence, 11897 is only a multiple of 1 and 11897.

Since 11897 is a prime number, 11897 is also a deficient number, that is to say 11897 is a natural integer that is strictly larger than the sum of its proper divisors, i.e., the divisors of 11897 without 11897 itself (that is 1, by definition!).

Parity of 11897

11897 is an odd number, because it is not evenly divisible by 2.

Is 11897 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 11897 is about 109.073.

Thus, the square root of 11897 is not an integer, and therefore 11897 is not a square number.

Anyway, 11897 is a prime number, and a prime number cannot be a perfect square.

What is the square number of 11897?
