Is 7901 a prime number? What are the divisors of 7901?

## Is 7901 a prime number?

Yes, 7901 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 7901, the only two divisors are 1 and 7901. Therefore 7901 is a prime number.

As a consequence, 7901 is only a multiple of 1 and 7901.

Since 7901 is a prime number, 7901 is also a deficient number, that is to say 7901 is a natural integer that is strictly larger than the sum of its proper divisors, i.e., the divisors of 7901 without 7901 itself (that is 1, by definition!).

## Parity of 7901

7901 is an odd number, because it is not evenly divisible by 2.

## Is 7901 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 7901 is about 88.888.

Thus, the square root of 7901 is not an integer, and therefore 7901 is not a square number.

Anyway, 7901 is a prime number, and a prime number cannot be a perfect square.

## What is the square number of 7901?

The square of a number (here 7901) is the result of the product of this number (7901) by itself (i.e., 7901 × 7901); the square of 7901 is sometimes called "raising 7901 to the power 2", or "7901 squared".

The square of 7901 is 62 425 801 because 7901 × 7901 = 79012 = 62 425 801.

As a consequence, 7901 is the square root of 62 425 801.

## Number of digits of 7901

7901 is a number with 4 digits.

## What are the multiples of 7901?

The multiples of 7901 are all integers evenly divisible by 7901, that is all numbers such that the remainder of the division by 7901 is zero. There are infinitely many multiples of 7901. The smallest multiples of 7901 are:

• 0: indeed, 0 is divisible by any natural number, and it is thus a multiple of 7901 too, since 0 × 7901 = 0
• 7901: indeed, 7901 is a multiple of itself, since 7901 is evenly divisible by 7901 (we have 7901 / 7901 = 1, so the remainder of this division is indeed zero)
• 15 802: indeed, 15 802 = 7901 × 2
• 23 703: indeed, 23 703 = 7901 × 3
• 31 604: indeed, 31 604 = 7901 × 4
• 39 505: indeed, 39 505 = 7901 × 5
• etc.
