41is an odd number,as it is not divisible by 2
The factors for 41 are all the numbers between -41 and 41 , which divide 41 without leaving any remainder. Since 41 divided by -41 is an integer, -41 is a factor of 41 .
Since 41 divided by -41 is a whole number, -41 is a factor of 41
Since 41 divided by -1 is a whole number, -1 is a factor of 41
Multiples of 41 are all integers divisible by 41 , i.e. the remainder of the full division by 41 is zero. There are infinite multiples of 41. The smallest multiples of 41 are:
It is possible to determine using mathematical techniques whether an integer is prime or not.
for 41, the answer is: yes, 41 is a prime number because it only has two different divisors: 1 and itself (41).
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 41). 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 6.403 ). 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.
