Is 9839 a prime number? What are the divisors of 9839?

Is 9839 a prime number?

Yes, 9839 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 9839, the only two divisors are 1 and 9839. Therefore 9839 is a prime number.

As a consequence, 9839 is only a multiple of 1 and 9839.

Since 9839 is a prime number, 9839 is also a deficient number, that is to say 9839 is a natural integer that is strictly larger than the sum of its proper divisors, i.e., the divisors of 9839 without 9839 itself (that is 1, by definition!).

Parity of 9839

9839 is an odd number, because it is not evenly divisible by 2.

Is 9839 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 9839 is about 99.192.

Thus, the square root of 9839 is not an integer, and therefore 9839 is not a square number.

Anyway, 9839 is a prime number, and a prime number cannot be a perfect square.

What is the square number of 9839?

The square of a number (here 9839) is the result of the product of this number (9839) by itself (i.e., 9839 × 9839); the square of 9839 is sometimes called "raising 9839 to the power 2", or "9839 squared".

The square of 9839 is 96 805 921 because 9839 × 9839 = 98392 = 96 805 921.

As a consequence, 9839 is the square root of 96 805 921.
