Is 1279 a prime number? What are the divisors of 1279?

## Is 1279 a prime number?

Yes, 1279 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 1279, the only two divisors are 1 and 1279. Therefore 1279 is a prime number.

As a consequence, 1279 is only a multiple of 1 and 1279.

Since 1279 is a prime number, 1279 is also a deficient number, that is to say 1279 is a natural integer that is strictly larger than the sum of its proper divisors, i.e., the divisors of 1279 without 1279 itself (that is 1, by definition!).

## Parity of 1279

1279 is an odd number, because it is not evenly divisible by 2.

## Is 1279 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 1279 is about 35.763.

Thus, the square root of 1279 is not an integer, and therefore 1279 is not a square number.

Anyway, 1279 is a prime number, and a prime number cannot be a perfect square.

## What is the square number of 1279?

The square of a number (here 1279) is the result of the product of this number (1279) by itself (i.e., 1279 × 1279); the square of 1279 is sometimes called "raising 1279 to the power 2", or "1279 squared".

The square of 1279 is 1 635 841 because 1279 × 1279 = 12792 = 1 635 841.

As a consequence, 1279 is the square root of 1 635 841.

## Number of digits of 1279

1279 is a number with 4 digits.

## What are the multiples of 1279?

The multiples of 1279 are all integers evenly divisible by 1279, that is all numbers such that the remainder of the division by 1279 is zero. There are infinitely many multiples of 1279. The smallest multiples of 1279 are:

• 0: indeed, 0 is divisible by any natural number, and it is thus a multiple of 1279 too, since 0 × 1279 = 0
• 1279: indeed, 1279 is a multiple of itself, since 1279 is evenly divisible by 1279 (we have 1279 / 1279 = 1, so the remainder of this division is indeed zero)
• 2 558: indeed, 2 558 = 1279 × 2
• 3 837: indeed, 3 837 = 1279 × 3
• 5 116: indeed, 5 116 = 1279 × 4
• 6 395: indeed, 6 395 = 1279 × 5
• etc.
