Is 371 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 371 is about 19.261.

Thus, the square root of 371 is not an integer, and therefore 371 is not a square number.

What is the square number of 371?

The square of a number (here 371) is the result of the product of this number (371) by itself (i.e., 371 × 371); the square of 371 is sometimes called "raising 371 to the power 2", or "371 squared".

The square of 371 is 137 641 because 371 × 371 = 3712 = 137 641.

As a consequence, 371 is the square root of 137 641.

Number of digits of 371

371 is a number with 3 digits.

What are the multiples of 371?

The multiples of 371 are all integers evenly divisible by 371, that is all numbers such that the remainder of the division by 371 is zero. There are infinitely many multiples of 371. The smallest multiples of 371 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 371). 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 19.261). 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.
