Is 662 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 662 is about 25.729.

Thus, the square root of 662 is not an integer, and therefore 662 is not a square number.

What is the square number of 662?

The square of a number (here 662) is the result of the product of this number (662) by itself (i.e., 662 × 662); the square of 662 is sometimes called "raising 662 to the power 2", or "662 squared".

The square of 662 is 438 244 because 662 × 662 = 6622 = 438 244.

As a consequence, 662 is the square root of 438 244.

Number of digits of 662

662 is a number with 3 digits.

What are the multiples of 662?

The multiples of 662 are all integers evenly divisible by 662, that is all numbers such that the remainder of the division by 662 is zero. There are infinitely many multiples of 662. The smallest multiples of 662 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 662). 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 25.729). 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.
