Is 347 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 347 is about 18.628.

Thus, the square root of 347 is not an integer, and therefore 347 is not a square number.

Anyway, 347 is a prime number, and a prime number cannot be a perfect square.

What is the square number of 347?

The square of a number (here 347) is the result of the product of this number (347) by itself (i.e., 347 × 347); the square of 347 is sometimes called "raising 347 to the power 2", or "347 squared".

The square of 347 is 120 409 because 347 × 347 = 3472 = 120 409.

As a consequence, 347 is the square root of 120 409.

Number of digits of 347

347 is a number with 3 digits.

What are the multiples of 347?

The multiples of 347 are all integers evenly divisible by 347, that is all numbers such that the remainder of the division by 347 is zero. There are infinitely many multiples of 347. The smallest multiples of 347 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 347). 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 18.628). 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.
