It is feasible to discover out using mathematical techniques whether a given integer is a element number or not.

You are watching: Is 33 a prime or composite number

For 33, the answer is: No, 33 is not a prime number.

The list of all hopeful divisors (i.e., the list of all integers that division 33) is together follows: 1, 3, 11, 33.

For 33 to it is in a element number, it would have been forced that 33 has only 2 divisors, i.e., itself and 1.

As a consequence:

For 33 to be a element number, that would have been forced that 33 has actually only two divisors, i.e., itself and 1.

However, 33 is a **semiprime** (also dubbed biprime or 2-almost-prime), because it is the product of a two non-necessarily distinct prime moment-g.com. Indeed, 33 = 3 x 11, where 3 and also 11 space both prime moment-g.com.

### Is 33 a deficient number?

Yes, 33 is a deficient number, the is to say 33 is a herbal number that is strictly bigger than the amount of its appropriate divisors, i.e., the divisors the 33 there is no 33 itself (that is 1 + 3 + 11 = 15).

## Parity that 33

33 is one odd number, since it is not evenly divisible through 2.

Find the end more:

## Is 33 a perfect square number?

A number is a perfect square (or a square number) if that square source is one integer; the is to say, that is the product of one integer v itself. Here, the square source of 33 is around 5.745.

Thus, the square source of 33 is no an integer, and also therefore 33 is not a square number.

## What is the square variety of 33?

The square that a number (here 33) is the result of the product of this number (33) by itself (i.e., 33 × 33); the square of 33 is sometimes referred to as "raising 33 come the strength 2", or "33 squared".

The square the 33 is 1 089 because 33 × 33 = 332 = 1 089.

As a consequence, 33 is the square root of 1 089.

## Number of number of 33

33 is a number v 2 digits.

## What space the multiples the 33?

The multiples of 33 are all integers evenly divisible by 33, that is every moment-g.com such the the remainder the the division by 33 is zero. There space infinitely plenty of multiples that 33. The smallest multiples that 33 are:

etc.## How to determine whether an integer is a prime number?

To recognize the primality that a number, several algorithms have the right to be used.The many naive method is come test all divisors strictly smaller to the variety of which we want to determine the primality (here 33).First, we can get rid of all even moment-g.com higher than 2 (and for this reason 4, 6, 8…).Then, we have the right to stop this check when us reach the square source of the number of which we desire to recognize the primality (here the square root is around 5.745).Historically, the sieve of Eratosthenes (dating indigenous the Greek mathematics) implements this technique in a relatively efficient manner.

More modern-day techniques include the sieve that Atkin, probability algorithms, and the cyclotomic AKS test.
