Is 6449 a prime number? What are the divisors of 6449?

## Is 6449 a prime number?

Yes, 6449 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 6449, the only two divisors are 1 and 6449. Therefore 6449 is a prime number.

As a consequence, 6449 is only a multiple of 1 and 6449.

Since 6449 is a prime number, 6449 is also a deficient number, that is to say 6449 is a natural integer that is strictly larger than the sum of its proper divisors, i.e., the divisors of 6449 without 6449 itself (that is 1, by definition!).

## Parity of 6449

6449 is an odd number, because it is not evenly divisible by 2.

## Is 6449 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 6449 is about 80.306.

Thus, the square root of 6449 is not an integer, and therefore 6449 is not a square number.

Anyway, 6449 is a prime number, and a prime number cannot be a perfect square.

## What is the square number of 6449?

The square of a number (here 6449) is the result of the product of this number (6449) by itself (i.e., 6449 × 6449); the square of 6449 is sometimes called "raising 6449 to the power 2", or "6449 squared".

The square of 6449 is 41 589 601 because 6449 × 6449 = 64492 = 41 589 601.

As a consequence, 6449 is the square root of 41 589 601.

## Number of digits of 6449
