Is 7723 a prime number? What are the divisors of 7723?

## Is 7723 a prime number?

Yes, 7723 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 7723, the only two divisors are 1 and 7723. Therefore 7723 is a prime number.

As a consequence, 7723 is only a multiple of 1 and 7723.

Since 7723 is a prime number, 7723 is also a deficient number, that is to say 7723 is a natural integer that is strictly larger than the sum of its proper divisors, i.e., the divisors of 7723 without 7723 itself (that is 1, by definition!).

## Parity of 7723

7723 is an odd number, because it is not evenly divisible by 2.

## Is 7723 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 7723 is about 87.881.

Thus, the square root of 7723 is not an integer, and therefore 7723 is not a square number.

Anyway, 7723 is a prime number, and a prime number cannot be a perfect square.

## What is the square number of 7723?

The square of a number (here 7723) is the result of the product of this number (7723) by itself (i.e., 7723 × 7723); the square of 7723 is sometimes called "raising 7723 to the power 2", or "7723 squared".

The square of 7723 is 59 644 729 because 7723 × 7723 = 77232 = 59 644 729.

As a consequence, 7723 is the square root of 59 644 729.

## Number of digits of 7723

7723 is a number with 4 digits.

## What are the multiples of 7723?

The multiples of 7723 are all integers evenly divisible by 7723, that is all numbers such that the remainder of the division by 7723 is zero. There are infinitely many multiples of 7723. The smallest multiples of 7723 are:

• 0: indeed, 0 is divisible by any natural number, and it is thus a multiple of 7723 too, since 0 × 7723 = 0
• 7723: indeed, 7723 is a multiple of itself, since 7723 is evenly divisible by 7723 (we have 7723 / 7723 = 1, so the remainder of this division is indeed zero)
• 15 446: indeed, 15 446 = 7723 × 2
• 23 169: indeed, 23 169 = 7723 × 3
• 30 892: indeed, 30 892 = 7723 × 4
• 38 615: indeed, 38 615 = 7723 × 5
• etc.
