For 332 to be a prime number, it would have been required that 332 has only two divisors, i.e., itself and 1.

Is 332 a deficient number?

Yes, 332 is a deficient number, that is to say 332 is a natural number that is strictly larger than the sum of its proper divisors, i.e., the divisors of 332 without 332 itself (that is 1 + 2 + 4 + 83 + 166 = 256).

Parity of 332

332 is an even number, because it is evenly divisible by 2: 332 / 2 = 166.

Is 332 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 332 is about 18.221.

Thus, the square root of 332 is not an integer, and therefore 332 is not a square number.

What is the square number of 332?

The square of a number (here 332) is the result of the product of this number (332) by itself (i.e., 332 × 332); the square of 332 is sometimes called "raising 332 to the power 2", or "332 squared".

The square of 332 is 110 224 because 332 × 332 = 332² = 110 224.

As a consequence, 332 is the square root of 110 224.

Number of digits of 332

332 is a number with 3 digits.

What are the multiples of 332?

The multiples of 332 are all integers evenly divisible by 332, that is all numbers such that the remainder of the division by 332 is zero. There are infinitely many multiples of 332. The smallest multiples of 332 are:

0: indeed, 0 is divisible by any natural number, and it is thus a multiple of 332 too, since 0 × 332 = 0
332: indeed, 332 is a multiple of itself, since 332 is evenly divisible by 332 (we have 332 / 332 = 1, so the remainder of this division is indeed zero)
664: indeed, 664 = 332 × 2
996: indeed, 996 = 332 × 3
1 328: indeed, 1 328 = 332 × 4
1 660: indeed, 1 660 = 332 × 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 332). 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 18.221). 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.
