## Is 246 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 246 is about 15.684.

Thus, the square root of 246 is not an integer, and therefore 246 is not a square number.

## What is the square number of 246?

The square of a number (here 246) is the result of the product of this number (246) by itself (i.e., 246 × 246); the square of 246 is sometimes called "raising 246 to the power 2", or "246 squared".

The square of 246 is 60 516 because 246 × 246 = 2462 = 60 516.

As a consequence, 246 is the square root of 60 516.

## Number of digits of 246

246 is a number with 3 digits.

## What are the multiples of 246?

The multiples of 246 are all integers evenly divisible by 246, that is all numbers such that the remainder of the division by 246 is zero. There are infinitely many multiples of 246. The smallest multiples of 246 are:

• 0: indeed, 0 is divisible by any natural number, and it is thus a multiple of 246 too, since 0 × 246 = 0
• 246: indeed, 246 is a multiple of itself, since 246 is evenly divisible by 246 (we have 246 / 246 = 1, so the remainder of this division is indeed zero)
• 492: indeed, 492 = 246 × 2
• 738: indeed, 738 = 246 × 3
• 984: indeed, 984 = 246 × 4
• 1 230: indeed, 1 230 = 246 × 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 246). 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 15.684). 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.
