Is 4909 a prime number? What are the divisors of 4909?

Is 4909 a prime number?

Yes, 4909 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 4909, the only two divisors are 1 and 4909. Therefore 4909 is a prime number.

As a consequence, 4909 is only a multiple of 1 and 4909.

Since 4909 is a prime number, 4909 is also a deficient number, that is to say 4909 is a natural integer that is strictly larger than the sum of its proper divisors, i.e., the divisors of 4909 without 4909 itself (that is 1, by definition!).

Parity of 4909

4909 is an odd number, because it is not evenly divisible by 2.

Is 4909 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 4909 is about 70.064.

Thus, the square root of 4909 is not an integer, and therefore 4909 is not a square number.

Anyway, 4909 is a prime number, and a prime number cannot be a perfect square.

What is the square number of 4909?

The square of a number (here 4909) is the result of the product of this number (4909) by itself (i.e., 4909 × 4909); the square of 4909 is sometimes called "raising 4909 to the power 2", or "4909 squared".

The square of 4909 is 24 098 281 because 4909 × 4909 = 49092 = 24 098 281.

As a consequence, 4909 is the square root of 24 098 281.
