## Is 979 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 979 is about 31.289.

Thus, the square root of 979 is not an integer, and therefore 979 is not a square number.

## What is the square number of 979?

The square of a number (here 979) is the result of the product of this number (979) by itself (i.e., 979 × 979); the square of 979 is sometimes called "raising 979 to the power 2", or "979 squared".

The square of 979 is 958 441 because 979 × 979 = 9792 = 958 441.

As a consequence, 979 is the square root of 958 441.

## Number of digits of 979

979 is a number with 3 digits.

## What are the multiples of 979?

The multiples of 979 are all integers evenly divisible by 979, that is all numbers such that the remainder of the division by 979 is zero. There are infinitely many multiples of 979. The smallest multiples of 979 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 979). 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 31.289). 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.
