## Is 372 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 372 is about 19.287.

Thus, the square root of 372 is not an integer, and therefore 372 is not a square number.

## What is the square number of 372?

The square of a number (here 372) is the result of the product of this number (372) by itself (i.e., 372 × 372); the square of 372 is sometimes called "raising 372 to the power 2", or "372 squared".

The square of 372 is 138 384 because 372 × 372 = 3722 = 138 384.

As a consequence, 372 is the square root of 138 384.

## Number of digits of 372

372 is a number with 3 digits.

## What are the multiples of 372?

The multiples of 372 are all integers evenly divisible by 372, that is all numbers such that the remainder of the division by 372 is zero. There are infinitely many multiples of 372. The smallest multiples of 372 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 372). 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 19.287). 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.
