Is 10103 a prime number? What are the divisors of 10103?

## Is 10103 a prime number?

Yes, 10103 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 10103, the only two divisors are 1 and 10103. Therefore 10103 is a prime number.

As a consequence, 10103 is only a multiple of 1 and 10103.

Since 10103 is a prime number, 10103 is also a deficient number, that is to say 10103 is a natural integer that is strictly larger than the sum of its proper divisors, i.e., the divisors of 10103 without 10103 itself (that is 1, by definition!).

## Parity of 10103

10103 is an odd number, because it is not evenly divisible by 2.

## Is 10103 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 10103 is about 100.514.

Thus, the square root of 10103 is not an integer, and therefore 10103 is not a square number.

Anyway, 10103 is a prime number, and a prime number cannot be a perfect square.

## What is the square number of 10103?

The square of a number (here 10103) is the result of the product of this number (10103) by itself (i.e., 10103 × 10103); the square of 10103 is sometimes called "raising 10103 to the power 2", or "10103 squared".

The square of 10103 is 102 070 609 because 10103 × 10103 = 101032 = 102 070 609.

As a consequence, 10103 is the square root of 102 070 609.

## Number of digits of 10103

10103 is a number with 5 digits.

## What are the multiples of 10103?

The multiples of 10103 are all integers evenly divisible by 10103, that is all numbers such that the remainder of the division by 10103 is zero. There are infinitely many multiples of 10103. The smallest multiples of 10103 are:

• 0: indeed, 0 is divisible by any natural number, and it is thus a multiple of 10103 too, since 0 × 10103 = 0
• 10103: indeed, 10103 is a multiple of itself, since 10103 is evenly divisible by 10103 (we have 10103 / 10103 = 1, so the remainder of this division is indeed zero)
• 20 206: indeed, 20 206 = 10103 × 2
• 30 309: indeed, 30 309 = 10103 × 3
• 40 412: indeed, 40 412 = 10103 × 4
• 50 515: indeed, 50 515 = 10103 × 5
• etc.
