Multiples of 2022 are all integers divisible by 2022 , i.e. the remainder of the full division by 2022 is zero. There are infinite multiples of 2022. The smallest multiples of 2022 are:
It is possible to determine using mathematical techniques whether an integer is prime or not.
for 2022, the answer is: No, 2022 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 2022). 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 44.967 ). 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.
