Multiples of 284 are all integers divisible by 284 , i.e. the remainder of the full division by 284 is zero. There are infinite multiples of 284. The smallest multiples of 284 are:
It is possible to determine using mathematical techniques whether an integer is prime or not.
for 284, the answer is: No, 284 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 284). 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 16.852 ). 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.
