Is 727 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 727 is about 26.963.

Thus, the square root of 727 is not an integer, and therefore 727 is not a square number.

Anyway, 727 is a prime number, and a prime number cannot be a perfect square.

What is the square number of 727?

The square of a number (here 727) is the result of the product of this number (727) by itself (i.e., 727 × 727); the square of 727 is sometimes called "raising 727 to the power 2", or "727 squared".

The square of 727 is 528 529 because 727 × 727 = 7272 = 528 529.

As a consequence, 727 is the square root of 528 529.

Number of digits of 727

727 is a number with 3 digits.

What are the multiples of 727?

The multiples of 727 are all integers evenly divisible by 727, that is all numbers such that the remainder of the division by 727 is zero. There are infinitely many multiples of 727. The smallest multiples of 727 are:

How to determine whether an integer is a prime number?

To determine the primality of a number, several algorithms can be used. The most naive technique is to test all divisors strictly smaller to the number of which we want to determine the primality (here 727). First, we can eliminate all even numbers greater than 2 (and hence 4, 6, 8…). Then, we can stop this check when we reach the square root of the number of which we want to determine the primality (here the square root is about 26.963). Historically, the sieve of Eratosthenes (dating from the Greek mathematics) implements this technique in a relatively efficient manner.

More modern techniques include the sieve of Atkin, probabilistic algorithms, and the cyclotomic AKS test.
