Is 40531 a prime number? What are the divisors of 40531?

## Is 40531 a prime number?

Yes, 40531 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 40531, the only two divisors are 1 and 40531. Therefore 40531 is a prime number.

As a consequence, 40531 is only a multiple of 1 and 40531.

Since 40531 is a prime number, 40531 is also a deficient number, that is to say 40531 is a natural integer that is strictly larger than the sum of its proper divisors, i.e., the divisors of 40531 without 40531 itself (that is 1, by definition!).

## Parity of 40531

40531 is an odd number, because it is not evenly divisible by 2.

## Is 40531 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 40531 is about 201.323.

Thus, the square root of 40531 is not an integer, and therefore 40531 is not a square number.

Anyway, 40531 is a prime number, and a prime number cannot be a perfect square.

## What is the square number of 40531?

The square of a number (here 40531) is the result of the product of this number (40531) by itself (i.e., 40531 × 40531); the square of 40531 is sometimes called "raising 40531 to the power 2", or "40531 squared".

The square of 40531 is 1 642 761 961 because 40531 × 40531 = 405312 = 1 642 761 961.

As a consequence, 40531 is the square root of 1 642 761 961.

## Number of digits of 40531

40531 is a number with 5 digits.

## What are the multiples of 40531?

• 0: indeed, 0 is divisible by any natural number, and it is thus a multiple of 40531 too, since 0 × 40531 = 0
• 40531: indeed, 40531 is a multiple of itself, since 40531 is evenly divisible by 40531 (we have 40531 / 40531 = 1, so the remainder of this division is indeed zero)
• 81 062: indeed, 81 062 = 40531 × 2
• 121 593: indeed, 121 593 = 40531 × 3
• 162 124: indeed, 162 124 = 40531 × 4
• 202 655: indeed, 202 655 = 40531 × 5
• etc.
