Multiples of 348 are all integers divisible by 348 , i.e. the remainder of the full division by 348 is zero. There are infinite multiples of 348. The smallest multiples of 348 are:
0 : in fact, 0 is divisible by any integer, so it is also a multiple of 348 since 0 × 348 = 0
348 : in fact, 348 is a multiple of itself, since 348 is divisible by 348 (it was 348 / 348 = 1, so the rest of this division is zero)
etc.
It is possible to determine using mathematical techniques whether an integer is prime or not.
for 348, the answer is: No, 348 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 348). 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 18.655 ). 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.
