Is 632 a deficient number?

Yes, 632 is a deficient number, that is to say 632 is a natural number that is strictly larger than the sum of its proper divisors, i.e., the divisors of 632 without 632 itself (that is 1 + 2 + 4 + 8 + 79 + 158 + 316 = 568).

Parity of 632

Is 632 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 632 is about 25.140.

Thus, the square root of 632 is not an integer, and therefore 632 is not a square number.

What is the square number of 632?

The square of a number (here 632) is the result of the product of this number (632) by itself (i.e., 632 × 632); the square of 632 is sometimes called "raising 632 to the power 2", or "632 squared".

The square of 632 is 399 424 because 632 × 632 = 632² = 399 424.

As a consequence, 632 is the square root of 399 424.

Number of digits of 632

632 is a number with 3 digits.

What are the multiples of 632?

The multiples of 632 are all integers evenly divisible by 632, that is all numbers such that the remainder of the division by 632 is zero. There are infinitely many multiples of 632. The smallest multiples of 632 are:

0: indeed, 0 is divisible by any natural number, and it is thus a multiple of 632 too, since 0 × 632 = 0
632: indeed, 632 is a multiple of itself, since 632 is evenly divisible by 632 (we have 632 / 632 = 1, so the remainder of this division is indeed zero)
1 264: indeed, 1 264 = 632 × 2
1 896: indeed, 1 896 = 632 × 3
2 528: indeed, 2 528 = 632 × 4
3 160: indeed, 3 160 = 632 × 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 632). 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 25.140). 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.
