271is an odd number,as it is not divisible by 2
The factors for 271 are all the numbers between -271 and 271 , which divide 271 without leaving any remainder. Since 271 divided by -271 is an integer, -271 is a factor of 271 .
Since 271 divided by -271 is a whole number, -271 is a factor of 271
Since 271 divided by -1 is a whole number, -1 is a factor of 271
Since 271 divided by 1 is a whole number, 1 is a factor of 271
Multiples of 271 are all integers divisible by 271 , i.e. the remainder of the full division by 271 is zero. There are infinite multiples of 271. The smallest multiples of 271 are:
0 : in fact, 0 is divisible by any integer, so it is also a multiple of 271 since 0 × 271 = 0
271 : in fact, 271 is a multiple of itself, since 271 is divisible by 271 (it was 271 / 271 = 1, so the rest of this division is zero)
It is possible to determine using mathematical techniques whether an integer is prime or not.
for 271, the answer is: yes, 271 is a prime number because it only has two different divisors: 1 and itself (271).
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 271). 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 16.462 ). 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.
