## Is 176 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 176 is about 13.266.

Thus, the square root of 176 is not an integer, and therefore 176 is not a square number.

## What is the square number of 176?

The square of a number (here 176) is the result of the product of this number (176) by itself (i.e., 176 × 176); the square of 176 is sometimes called "raising 176 to the power 2", or "176 squared".

The square of 176 is 30 976 because 176 × 176 = 1762 = 30 976.

As a consequence, 176 is the square root of 30 976.

## Number of digits of 176

176 is a number with 3 digits.

## What are the multiples of 176?

The multiples of 176 are all integers evenly divisible by 176, that is all numbers such that the remainder of the division by 176 is zero. There are infinitely many multiples of 176. The smallest multiples of 176 are:

• 0: indeed, 0 is divisible by any natural number, and it is thus a multiple of 176 too, since 0 × 176 = 0
• 176: indeed, 176 is a multiple of itself, since 176 is evenly divisible by 176 (we have 176 / 176 = 1, so the remainder of this division is indeed zero)
• 352: indeed, 352 = 176 × 2
• 528: indeed, 528 = 176 × 3
• 704: indeed, 704 = 176 × 4
• 880: indeed, 880 = 176 × 5
• etc.

## 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 176). 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 13.266). 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.
