Is 935 a prime number?

It is possible to find out using mathematical methods whether a given integer is a prime number or not.

For 935, the answer is: No, 935 is not a prime number.

The list of all positive divisors (i.e., the list of all integers that divide 935) is as follows: 1, 5, 11, 17, 55, 85, 187, 935.

For 935 to be a prime number, it would have been required that 935 has only two divisors, i.e., itself and 1.

What is a prime number?

Actually, one can immediately see that 935 cannot be prime, because 5 is one of its divisors: indeed, a number ending with 0 or 5 has necessarily 5 among its divisors. The last digit of 935 is 5, so it is divisible by 5 and is therefore not prime.

As a consequence:

935 is a multiple of 1
935 is a multiple of 5
935 is a multiple of 11
935 is a multiple of 17
935 is a multiple of 55
935 is a multiple of 85
935 is a multiple of 187

For 935 to be a prime number, it would have been required that 935 has only two divisors, i.e., itself and 1.

Is 935 a deficient number?

Yes, 935 is a deficient number, that is to say 935 is a natural number that is strictly larger than the sum of its proper divisors, i.e., the divisors of 935 without 935 itself (that is 1 + 5 + 11 + 17 + 55 + 85 + 187 = 361).

Parity of 935

Is 935 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 935 is about 30.578.

Thus, the square root of 935 is not an integer, and therefore 935 is not a square number.

What is the square number of 935?

The square of a number (here 935) is the result of the product of this number (935) by itself (i.e., 935 × 935); the square of 935 is sometimes called "raising 935 to the power 2", or "935 squared".

The square of 935 is 874 225 because 935 × 935 = 935² = 874 225.

As a consequence, 935 is the square root of 874 225.

Number of digits of 935

935 is a number with 3 digits.

What are the multiples of 935?

The multiples of 935 are all integers evenly divisible by 935, that is all numbers such that the remainder of the division by 935 is zero. There are infinitely many multiples of 935. The smallest multiples of 935 are:

0: indeed, 0 is divisible by any natural number, and it is thus a multiple of 935 too, since 0 × 935 = 0
935: indeed, 935 is a multiple of itself, since 935 is evenly divisible by 935 (we have 935 / 935 = 1, so the remainder of this division is indeed zero)
1 870: indeed, 1 870 = 935 × 2
2 805: indeed, 2 805 = 935 × 3
3 740: indeed, 3 740 = 935 × 4
4 675: indeed, 4 675 = 935 × 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 935). 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 30.578). 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.
