241is an odd number,as it is not divisible by 2
The factors for 241 are all the numbers between -241 and 241 , which divide 241 without leaving any remainder. Since 241 divided by -241 is an integer, -241 is a factor of 241 .
Since 241 divided by -241 is a whole number, -241 is a factor of 241
Since 241 divided by -1 is a whole number, -1 is a factor of 241
Multiples of 241 are all integers divisible by 241 , i.e. the remainder of the full division by 241 is zero. There are infinite multiples of 241. The smallest multiples of 241 are:
It is possible to determine using mathematical techniques whether an integer is prime or not.
for 241, the answer is: yes, 241 is a prime number because it only has two different divisors: 1 and itself (241).
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 241). 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 15.524 ). 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.
