2711is an odd number,as it is not divisible by 2
The factors for 2711 are all the numbers between -2711 and 2711 , which divide 2711 without leaving any remainder. Since 2711 divided by -2711 is an integer, -2711 is a factor of 2711 .
Since 2711 divided by -2711 is a whole number, -2711 is a factor of 2711
Since 2711 divided by -1 is a whole number, -1 is a factor of 2711
Since 2711 divided by 1 is a whole number, 1 is a factor of 2711
Multiples of 2711 are all integers divisible by 2711 , i.e. the remainder of the full division by 2711 is zero. There are infinite multiples of 2711. The smallest multiples of 2711 are:
0 : in fact, 0 is divisible by any integer, so it is also a multiple of 2711 since 0 × 2711 = 0
2711 : in fact, 2711 is a multiple of itself, since 2711 is divisible by 2711 (it was 2711 / 2711 = 1, so the rest of this division is zero)
5422: in fact, 5422 = 2711 × 2
8133: in fact, 8133 = 2711 × 3
10844: in fact, 10844 = 2711 × 4
13555: in fact, 13555 = 2711 × 5
etc.
It is possible to determine using mathematical techniques whether an integer is prime or not.
for 2711, the answer is: yes, 2711 is a prime number because it only has two different divisors: 1 and itself (2711).
To know the primality of an integer, we can use several algorithms. The most naive is to try all divisors below the number you want to know if it is prime (in our case 2711). We can already eliminate even numbers bigger than 2 (then 4 , 6 , 8 ...). Besides, we can stop at the square root of the number in question (here 52.067 ). Historically, the Eratosthenes screen (which dates back to Antiquity) uses this technique relatively effectively.
More modern techniques include the Atkin screen, probabilistic tests, or the cyclotomic test.
