In addition we can say of the number 8006 that it is even
8006 is an even number, as it is divisible by 2 : 8006/2 = 4003
The factors for 8006 are all the numbers between -8006 and 8006 , which divide 8006 without leaving any remainder. Since 8006 divided by -8006 is an integer, -8006 is a factor of 8006 .
Since 8006 divided by -8006 is a whole number, -8006 is a factor of 8006
Since 8006 divided by -4003 is a whole number, -4003 is a factor of 8006
Since 8006 divided by -2 is a whole number, -2 is a factor of 8006
Since 8006 divided by -1 is a whole number, -1 is a factor of 8006
Multiples of 8006 are all integers divisible by 8006 , i.e. the remainder of the full division by 8006 is zero. There are infinite multiples of 8006. The smallest multiples of 8006 are:
It is possible to determine using mathematical techniques whether an integer is prime or not.
for 8006, the answer is: No, 8006 is not a prime number.
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 8006). 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 89.476 ). 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.
