In addition we can say of the number 482 that it is even
482 is an even number, as it is divisible by 2 : 482/2 = 241
The factors for 482 are all the numbers between -482 and 482 , which divide 482 without leaving any remainder. Since 482 divided by -482 is an integer, -482 is a factor of 482 .
Since 482 divided by -482 is a whole number, -482 is a factor of 482
Since 482 divided by -241 is a whole number, -241 is a factor of 482
Since 482 divided by -2 is a whole number, -2 is a factor of 482
Since 482 divided by -1 is a whole number, -1 is a factor of 482
Multiples of 482 are all integers divisible by 482 , i.e. the remainder of the full division by 482 is zero. There are infinite multiples of 482. The smallest multiples of 482 are:
It is possible to determine using mathematical techniques whether an integer is prime or not.
for 482, the answer is: No, 482 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 482). 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 21.954 ). 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.
