Is 652 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 652 is about 25.534.

Thus, the square root of 652 is not an integer, and therefore 652 is not a square number.

What is the square number of 652?

The square of a number (here 652) is the result of the product of this number (652) by itself (i.e., 652 × 652); the square of 652 is sometimes called "raising 652 to the power 2", or "652 squared".

The square of 652 is 425 104 because 652 × 652 = 652² = 425 104.

As a consequence, 652 is the square root of 425 104.

Number of digits of 652

652 is a number with 3 digits.

What are the multiples of 652?

The multiples of 652 are all integers evenly divisible by 652, that is all numbers such that the remainder of the division by 652 is zero. There are infinitely many multiples of 652. The smallest multiples of 652 are:

0: indeed, 0 is divisible by any natural number, and it is thus a multiple of 652 too, since 0 × 652 = 0
652: indeed, 652 is a multiple of itself, since 652 is evenly divisible by 652 (we have 652 / 652 = 1, so the remainder of this division is indeed zero)
1 304: indeed, 1 304 = 652 × 2
1 956: indeed, 1 956 = 652 × 3
2 608: indeed, 2 608 = 652 × 4
3 260: indeed, 3 260 = 652 × 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 652). 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 25.534). 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.
