Is 1889 a prime number? What are the divisors of 1889?

Is 1889 a prime number?

Yes, 1889 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 1889, the only two divisors are 1 and 1889. Therefore 1889 is a prime number.

As a consequence, 1889 is only a multiple of 1 and 1889.

Therefore year 1889 was a prime year.

Since 1889 is a prime number, 1889 is also a deficient number, that is to say 1889 is a natural integer that is strictly larger than the sum of its proper divisors, i.e., the divisors of 1889 without 1889 itself (that is 1, by definition!).

Parity of 1889

1889 is an odd number, because it is not evenly divisible by 2.

Is 1889 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 1889 is about 43.463.

Thus, the square root of 1889 is not an integer, and therefore 1889 is not a square number.

Anyway, 1889 is a prime number, and a prime number cannot be a perfect square.

What is the square number of 1889?

The square of a number (here 1889) is the result of the product of this number (1889) by itself (i.e., 1889 × 1889); the square of 1889 is sometimes called "raising 1889 to the power 2", or "1889 squared".

The square of 1889 is 3 568 321 because 1889 × 1889 = 18892 = 3 568 321.

As a consequence, 1889 is the square root of 3 568 321.
