For 544 to be a prime number, it would have been required that 544 has only two divisors, i.e., itself and 1.

Is 544 a deficient number?

No, 544 is not a deficient number: to be deficient, 544 should have been such that 544 is larger than the sum of its proper divisors, i.e., the divisors of 544 without 544 itself (that is 1 + 2 + 4 + 8 + 16 + 17 + 32 + 34 + 68 + 136 + 272 = 590).

In fact, 544 is an abundant number; 544 is strictly smaller than the sum of its proper divisors (that is 1 + 2 + 4 + 8 + 16 + 17 + 32 + 34 + 68 + 136 + 272 = 590). The smallest abundant number is 12.

Parity of 544

Is 544 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 544 is about 23.324.

Thus, the square root of 544 is not an integer, and therefore 544 is not a square number.

What is the square number of 544?

The square of a number (here 544) is the result of the product of this number (544) by itself (i.e., 544 × 544); the square of 544 is sometimes called "raising 544 to the power 2", or "544 squared".

The square of 544 is 295 936 because 544 × 544 = 544² = 295 936.

As a consequence, 544 is the square root of 295 936.

Number of digits of 544

544 is a number with 3 digits.

What are the multiples of 544?

The multiples of 544 are all integers evenly divisible by 544, that is all numbers such that the remainder of the division by 544 is zero. There are infinitely many multiples of 544. The smallest multiples of 544 are:

0: indeed, 0 is divisible by any natural number, and it is thus a multiple of 544 too, since 0 × 544 = 0
544: indeed, 544 is a multiple of itself, since 544 is evenly divisible by 544 (we have 544 / 544 = 1, so the remainder of this division is indeed zero)
1 088: indeed, 1 088 = 544 × 2
1 632: indeed, 1 632 = 544 × 3
2 176: indeed, 2 176 = 544 × 4
2 720: indeed, 2 720 = 544 × 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 544). 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 23.324). 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.
