Is 465 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 465 is about 21.564.

Thus, the square root of 465 is not an integer, and therefore 465 is not a square number.

What is the square number of 465?

The square of a number (here 465) is the result of the product of this number (465) by itself (i.e., 465 × 465); the square of 465 is sometimes called "raising 465 to the power 2", or "465 squared".

The square of 465 is 216 225 because 465 × 465 = 4652 = 216 225.

As a consequence, 465 is the square root of 216 225.

Number of digits of 465

465 is a number with 3 digits.

What are the multiples of 465?

The multiples of 465 are all integers evenly divisible by 465, that is all numbers such that the remainder of the division by 465 is zero. There are infinitely many multiples of 465. The smallest multiples of 465 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 465). 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 21.564). 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.
