## Is 234 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 234 is about 15.297.

Thus, the square root of 234 is not an integer, and therefore 234 is not a square number.

## What is the square number of 234?

The square of a number (here 234) is the result of the product of this number (234) by itself (i.e., 234 × 234); the square of 234 is sometimes called "raising 234 to the power 2", or "234 squared".

The square of 234 is 54 756 because 234 × 234 = 2342 = 54 756.

As a consequence, 234 is the square root of 54 756.

## Number of digits of 234

234 is a number with 3 digits.

## What are the multiples of 234?

The multiples of 234 are all integers evenly divisible by 234, that is all numbers such that the remainder of the division by 234 is zero. There are infinitely many multiples of 234. The smallest multiples of 234 are:

• 0: indeed, 0 is divisible by any natural number, and it is thus a multiple of 234 too, since 0 × 234 = 0
• 234: indeed, 234 is a multiple of itself, since 234 is evenly divisible by 234 (we have 234 / 234 = 1, so the remainder of this division is indeed zero)
• 468: indeed, 468 = 234 × 2
• 702: indeed, 702 = 234 × 3
• 936: indeed, 936 = 234 × 4
• 1 170: indeed, 1 170 = 234 × 5
• etc.

## 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 234). 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 15.297). 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.
