Is 412 a deficient number?

Yes, 412 is a deficient number, that is to say 412 is a natural number that is strictly larger than the sum of its proper divisors, i.e., the divisors of 412 without 412 itself (that is 1 + 2 + 4 + 103 + 206 = 316).

Parity of 412

412 is an even number, because it is evenly divisible by 2: 412 / 2 = 206.

Is 412 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 412 is about 20.298.

Thus, the square root of 412 is not an integer, and therefore 412 is not a square number.

What is the square number of 412?

The square of a number (here 412) is the result of the product of this number (412) by itself (i.e., 412 × 412); the square of 412 is sometimes called "raising 412 to the power 2", or "412 squared".

The square of 412 is 169 744 because 412 × 412 = 412² = 169 744.

As a consequence, 412 is the square root of 169 744.

Number of digits of 412

412 is a number with 3 digits.

What are the multiples of 412?

The multiples of 412 are all integers evenly divisible by 412, that is all numbers such that the remainder of the division by 412 is zero. There are infinitely many multiples of 412. The smallest multiples of 412 are:

0: indeed, 0 is divisible by any natural number, and it is thus a multiple of 412 too, since 0 × 412 = 0
412: indeed, 412 is a multiple of itself, since 412 is evenly divisible by 412 (we have 412 / 412 = 1, so the remainder of this division is indeed zero)
824: indeed, 824 = 412 × 2
1 236: indeed, 1 236 = 412 × 3
1 648: indeed, 1 648 = 412 × 4
2 060: indeed, 2 060 = 412 × 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 412). 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 20.298). 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.
