Is 9749 a prime number? What are the divisors of 9749?

Is 9749 a prime number?

Yes, 9749 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 9749, the only two divisors are 1 and 9749. Therefore 9749 is a prime number.

As a consequence, 9749 is only a multiple of 1 and 9749.

Since 9749 is a prime number, 9749 is also a deficient number, that is to say 9749 is a natural integer that is strictly larger than the sum of its proper divisors, i.e., the divisors of 9749 without 9749 itself (that is 1, by definition!).

Parity of 9749

9749 is an odd number, because it is not evenly divisible by 2.

Is 9749 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 9749 is about 98.737.

Thus, the square root of 9749 is not an integer, and therefore 9749 is not a square number.

Anyway, 9749 is a prime number, and a prime number cannot be a perfect square.

What is the square number of 9749?
