Is 7823 a prime number? What are the divisors of 7823?

## Is 7823 a prime number?

Yes, 7823 is a prime number.

Indeed, the definition of a prime numbers is to have only two distinct positive divisors, 1 and itself. A number is a divisor of another number when the remainder of Euclid’s division of the second one by the first one is zero. Concerning the number 7823, the only two divisors are 1 and 7823. Therefore 7823 is a prime number.

As a consequence, 7823 is only a multiple of 1 and 7823.

Since 7823 is a prime number, 7823 is also a deficient number, that is to say 7823 is a natural integer that is strictly larger than the sum of its proper divisors, i.e., the divisors of 7823 without 7823 itself (that is 1, by definition!).

## Parity of 7823

7823 is an odd number, because it is not evenly divisible by 2.

## Is 7823 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 7823 is about 88.448.

Thus, the square root of 7823 is not an integer, and therefore 7823 is not a square number.

Anyway, 7823 is a prime number, and a prime number cannot be a perfect square.

## What is the square number of 7823?

The square of a number (here 7823) is the result of the product of this number (7823) by itself (i.e., 7823 × 7823); the square of 7823 is sometimes called "raising 7823 to the power 2", or "7823 squared".

The square of 7823 is 61 199 329 because 7823 × 7823 = 78232 = 61 199 329.

As a consequence, 7823 is the square root of 61 199 329.

## Number of digits of 7823

7823 is a number with 4 digits.

## What are the multiples of 7823?

The multiples of 7823 are all integers evenly divisible by 7823, that is all numbers such that the remainder of the division by 7823 is zero. There are infinitely many multiples of 7823. The smallest multiples of 7823 are:

• 0: indeed, 0 is divisible by any natural number, and it is thus a multiple of 7823 too, since 0 × 7823 = 0
• 7823: indeed, 7823 is a multiple of itself, since 7823 is evenly divisible by 7823 (we have 7823 / 7823 = 1, so the remainder of this division is indeed zero)
• 15 646: indeed, 15 646 = 7823 × 2
• 23 469: indeed, 23 469 = 7823 × 3
• 31 292: indeed, 31 292 = 7823 × 4
• 39 115: indeed, 39 115 = 7823 × 5
• etc.
