Is 7879 a prime number? What are the divisors of 7879?

## Is 7879 a prime number?

Yes, 7879 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 7879, the only two divisors are 1 and 7879. Therefore 7879 is a prime number.

As a consequence, 7879 is only a multiple of 1 and 7879.

Since 7879 is a prime number, 7879 is also a deficient number, that is to say 7879 is a natural integer that is strictly larger than the sum of its proper divisors, i.e., the divisors of 7879 without 7879 itself (that is 1, by definition!).

## Parity of 7879

7879 is an odd number, because it is not evenly divisible by 2.

## Is 7879 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 7879 is about 88.764.

Thus, the square root of 7879 is not an integer, and therefore 7879 is not a square number.

Anyway, 7879 is a prime number, and a prime number cannot be a perfect square.

## What is the square number of 7879?

The square of a number (here 7879) is the result of the product of this number (7879) by itself (i.e., 7879 × 7879); the square of 7879 is sometimes called "raising 7879 to the power 2", or "7879 squared".

The square of 7879 is 62 078 641 because 7879 × 7879 = 78792 = 62 078 641.

As a consequence, 7879 is the square root of 62 078 641.

## Number of digits of 7879

7879 is a number with 4 digits.

## What are the multiples of 7879?
