Is 2749 a prime number? What are the divisors of 2749?

Is 2749 a prime number?

Yes, 2749 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 2749, the only two divisors are 1 and 2749. Therefore 2749 is a prime number.

As a consequence, 2749 is only a multiple of 1 and 2749.

Since 2749 is a prime number, 2749 is also a deficient number, that is to say 2749 is a natural integer that is strictly larger than the sum of its proper divisors, i.e., the divisors of 2749 without 2749 itself (that is 1, by definition!).

Parity of 2749

2749 is an odd number, because it is not evenly divisible by 2.

Is 2749 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 2749 is about 52.431.

Thus, the square root of 2749 is not an integer, and therefore 2749 is not a square number.

Anyway, 2749 is a prime number, and a prime number cannot be a perfect square.

What is the square number of 2749?

The square of a number (here 2749) is the result of the product of this number (2749) by itself (i.e., 2749 × 2749); the square of 2749 is sometimes called "raising 2749 to the power 2", or "2749 squared".

The square of 2749 is 7 557 001 because 2749 × 2749 = 27492 = 7 557 001.

As a consequence, 2749 is the square root of 7 557 001.
