## Is 174 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 174 is about 13.191.

Thus, the square root of 174 is not an integer, and therefore 174 is not a square number.

## What is the square number of 174?

The square of a number (here 174) is the result of the product of this number (174) by itself (i.e., 174 × 174); the square of 174 is sometimes called "raising 174 to the power 2", or "174 squared".

The square of 174 is 30 276 because 174 × 174 = 1742 = 30 276.

As a consequence, 174 is the square root of 30 276.

## Number of digits of 174

174 is a number with 3 digits.

## What are the multiples of 174?

The multiples of 174 are all integers evenly divisible by 174, that is all numbers such that the remainder of the division by 174 is zero. There are infinitely many multiples of 174. The smallest multiples of 174 are:

• 0: indeed, 0 is divisible by any natural number, and it is thus a multiple of 174 too, since 0 × 174 = 0
• 174: indeed, 174 is a multiple of itself, since 174 is evenly divisible by 174 (we have 174 / 174 = 1, so the remainder of this division is indeed zero)
• 348: indeed, 348 = 174 × 2
• 522: indeed, 522 = 174 × 3
• 696: indeed, 696 = 174 × 4
• 870: indeed, 870 = 174 × 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 174). 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 13.191). 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.
