Is 536 a deficient number?

Yes, 536 is a deficient number, that is to say 536 is a natural number that is strictly larger than the sum of its proper divisors, i.e., the divisors of 536 without 536 itself (that is 1 + 2 + 4 + 8 + 67 + 134 + 268 = 484).

Parity of 536

536 is an even number, because it is evenly divisible by 2: 536 / 2 = 268.

Is 536 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 536 is about 23.152.

Thus, the square root of 536 is not an integer, and therefore 536 is not a square number.

What is the square number of 536?

The square of a number (here 536) is the result of the product of this number (536) by itself (i.e., 536 × 536); the square of 536 is sometimes called "raising 536 to the power 2", or "536 squared".

The square of 536 is 287 296 because 536 × 536 = 536² = 287 296.

As a consequence, 536 is the square root of 287 296.

Number of digits of 536

536 is a number with 3 digits.

What are the multiples of 536?

The multiples of 536 are all integers evenly divisible by 536, that is all numbers such that the remainder of the division by 536 is zero. There are infinitely many multiples of 536. The smallest multiples of 536 are:

0: indeed, 0 is divisible by any natural number, and it is thus a multiple of 536 too, since 0 × 536 = 0
536: indeed, 536 is a multiple of itself, since 536 is evenly divisible by 536 (we have 536 / 536 = 1, so the remainder of this division is indeed zero)
1 072: indeed, 1 072 = 536 × 2
1 608: indeed, 1 608 = 536 × 3
2 144: indeed, 2 144 = 536 × 4
2 680: indeed, 2 680 = 536 × 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 536). 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 23.152). 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.
