Is 7643 a prime number? What are the divisors of 7643?

## Is 7643 a prime number?

Yes, 7643 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 7643, the only two divisors are 1 and 7643. Therefore 7643 is a prime number.

As a consequence, 7643 is only a multiple of 1 and 7643.

Since 7643 is a prime number, 7643 is also a deficient number, that is to say 7643 is a natural integer that is strictly larger than the sum of its proper divisors, i.e., the divisors of 7643 without 7643 itself (that is 1, by definition!).

## Parity of 7643

7643 is an odd number, because it is not evenly divisible by 2.

## Is 7643 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 7643 is about 87.424.

Thus, the square root of 7643 is not an integer, and therefore 7643 is not a square number.

Anyway, 7643 is a prime number, and a prime number cannot be a perfect square.

## What is the square number of 7643?

The square of a number (here 7643) is the result of the product of this number (7643) by itself (i.e., 7643 × 7643); the square of 7643 is sometimes called "raising 7643 to the power 2", or "7643 squared".

The square of 7643 is 58 415 449 because 7643 × 7643 = 76432 = 58 415 449.

As a consequence, 7643 is the square root of 58 415 449.

## Number of digits of 7643

7643 is a number with 4 digits.

## What are the multiples of 7643?

• 0: indeed, 0 is divisible by any natural number, and it is thus a multiple of 7643 too, since 0 × 7643 = 0
• 7643: indeed, 7643 is a multiple of itself, since 7643 is evenly divisible by 7643 (we have 7643 / 7643 = 1, so the remainder of this division is indeed zero)
• 15 286: indeed, 15 286 = 7643 × 2
• 22 929: indeed, 22 929 = 7643 × 3
• 30 572: indeed, 30 572 = 7643 × 4
• 38 215: indeed, 38 215 = 7643 × 5
• etc.
