## Is 975 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 975 is about 31.225.

Thus, the square root of 975 is not an integer, and therefore 975 is not a square number.

## What is the square number of 975?

The square of a number (here 975) is the result of the product of this number (975) by itself (i.e., 975 × 975); the square of 975 is sometimes called "raising 975 to the power 2", or "975 squared".

The square of 975 is 950 625 because 975 × 975 = 9752 = 950 625.

As a consequence, 975 is the square root of 950 625.

## Number of digits of 975

975 is a number with 3 digits.

## What are the multiples of 975?

The multiples of 975 are all integers evenly divisible by 975, that is all numbers such that the remainder of the division by 975 is zero. There are infinitely many multiples of 975. The smallest multiples of 975 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 975). 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 31.225). 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.
