Is 1873 a prime number? What are the divisors of 1873?

## Is 1873 a prime number?

Yes, 1873 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 1873, the only two divisors are 1 and 1873. Therefore 1873 is a prime number.

As a consequence, 1873 is only a multiple of 1 and 1873.

Therefore year 1873 was a prime year.

Since 1873 is a prime number, 1873 is also a deficient number, that is to say 1873 is a natural integer that is strictly larger than the sum of its proper divisors, i.e., the divisors of 1873 without 1873 itself (that is 1, by definition!).

## Parity of 1873

1873 is an odd number, because it is not evenly divisible by 2.

## Is 1873 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 1873 is about 43.278.

Thus, the square root of 1873 is not an integer, and therefore 1873 is not a square number.

Anyway, 1873 is a prime number, and a prime number cannot be a perfect square.

## What is the square number of 1873?

The square of a number (here 1873) is the result of the product of this number (1873) by itself (i.e., 1873 × 1873); the square of 1873 is sometimes called "raising 1873 to the power 2", or "1873 squared".

The square of 1873 is 3 508 129 because 1873 × 1873 = 18732 = 3 508 129.

As a consequence, 1873 is the square root of 3 508 129.

## Number of digits of 1873

1873 is a number with 4 digits.

## What are the multiples of 1873?

The multiples of 1873 are all integers evenly divisible by 1873, that is all numbers such that the remainder of the division by 1873 is zero. There are infinitely many multiples of 1873. The smallest multiples of 1873 are:

• 0: indeed, 0 is divisible by any natural number, and it is thus a multiple of 1873 too, since 0 × 1873 = 0
• 1873: indeed, 1873 is a multiple of itself, since 1873 is evenly divisible by 1873 (we have 1873 / 1873 = 1, so the remainder of this division is indeed zero)
• 3 746: indeed, 3 746 = 1873 × 2
• 5 619: indeed, 5 619 = 1873 × 3
• 7 492: indeed, 7 492 = 1873 × 4
• 9 365: indeed, 9 365 = 1873 × 5
• etc.
