Is 7649 a prime number? What are the divisors of 7649?

## Is 7649 a prime number?

Yes, 7649 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 7649, the only two divisors are 1 and 7649. Therefore 7649 is a prime number.

As a consequence, 7649 is only a multiple of 1 and 7649.

Since 7649 is a prime number, 7649 is also a deficient number, that is to say 7649 is a natural integer that is strictly larger than the sum of its proper divisors, i.e., the divisors of 7649 without 7649 itself (that is 1, by definition!).

## Parity of 7649

7649 is an odd number, because it is not evenly divisible by 2.

## Is 7649 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 7649 is about 87.459.

Thus, the square root of 7649 is not an integer, and therefore 7649 is not a square number.

Anyway, 7649 is a prime number, and a prime number cannot be a perfect square.

## What is the square number of 7649?

The square of a number (here 7649) is the result of the product of this number (7649) by itself (i.e., 7649 × 7649); the square of 7649 is sometimes called "raising 7649 to the power 2", or "7649 squared".

The square of 7649 is 58 507 201 because 7649 × 7649 = 76492 = 58 507 201.

As a consequence, 7649 is the square root of 58 507 201.

## Number of digits of 7649
