Is 1399 a prime number? What are the divisors of 1399?

Is 1399 a prime number?

Yes, 1399 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 1399, the only two divisors are 1 and 1399. Therefore 1399 is a prime number.

As a consequence, 1399 is only a multiple of 1 and 1399.

Since 1399 is a prime number, 1399 is also a deficient number, that is to say 1399 is a natural integer that is strictly larger than the sum of its proper divisors, i.e., the divisors of 1399 without 1399 itself (that is 1, by definition!).

Parity of 1399

1399 is an odd number, because it is not evenly divisible by 2.

Is 1399 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 1399 is about 37.403.

Thus, the square root of 1399 is not an integer, and therefore 1399 is not a square number.

Anyway, 1399 is a prime number, and a prime number cannot be a perfect square.

What is the square number of 1399?

The square of a number (here 1399) is the result of the product of this number (1399) by itself (i.e., 1399 × 1399); the square of 1399 is sometimes called "raising 1399 to the power 2", or "1399 squared".

The square of 1399 is 1 957 201 because 1399 × 1399 = 13992 = 1 957 201.

As a consequence, 1399 is the square root of 1 957 201.

  • 0: indeed, 0 is divisible by any natural number, and it is thus a multiple of 1399 too, since 0 × 1399 = 0
  • 1399: indeed, 1399 is a multiple of itself, since 1399 is evenly divisible by 1399 (we have 1399 / 1399 = 1, so the remainder of this division is indeed zero)
  • 2 798: indeed, 2 798 = 1399 × 2
  • 4 197: indeed, 4 197 = 1399 × 3
  • 5 596: indeed, 5 596 = 1399 × 4
  • 6 995: indeed, 6 995 = 1399 × 5
  • etc.
