Is 770 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 770 is about 27.749.

Thus, the square root of 770 is not an integer, and therefore 770 is not a square number.

What is the square number of 770?

The square of a number (here 770) is the result of the product of this number (770) by itself (i.e., 770 × 770); the square of 770 is sometimes called "raising 770 to the power 2", or "770 squared".

The square of 770 is 592 900 because 770 × 770 = 7702 = 592 900.

As a consequence, 770 is the square root of 592 900.

Number of digits of 770

770 is a number with 3 digits.

What are the multiples of 770?

The multiples of 770 are all integers evenly divisible by 770, that is all numbers such that the remainder of the division by 770 is zero. There are infinitely many multiples of 770. The smallest multiples of 770 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 770). 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 27.749). 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.
