What are the multiples of 308?
Multiples of 308 are all integers divisible by 308 , i.e. the remainder of the full division by 308 is zero. There are infinite multiples of 308. The smallest multiples of 308 are:
0 : in fact, 0 is divisible by any integer, so it is also a multiple of 308 since 0 × 308 = 0
308 : in fact, 308 is a multiple of itself, since 308 is divisible by 308 (it was 308 / 308 = 1, so the rest of this division is zero)
etc.
Is 308 a prime number?
It is possible to determine using mathematical techniques whether an integer is prime or not.
for 308, the answer is: No, 308 is not a prime number.
How do you determine if a number is prime?
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 308). 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 17.55 ). 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.
