## Is 375 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 375 is about 19.365.

Thus, the square root of 375 is not an integer, and therefore 375 is not a square number.

## What is the square number of 375?

The square of a number (here 375) is the result of the product of this number (375) by itself (i.e., 375 × 375); the square of 375 is sometimes called "raising 375 to the power 2", or "375 squared".

The square of 375 is 140 625 because 375 × 375 = 3752 = 140 625.

As a consequence, 375 is the square root of 140 625.

## Number of digits of 375

375 is a number with 3 digits.

## What are the multiples of 375?

The multiples of 375 are all integers evenly divisible by 375, that is all numbers such that the remainder of the division by 375 is zero. There are infinitely many multiples of 375. The smallest multiples of 375 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 375). 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 19.365). 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.
