Multiples of 3220 are all integers divisible by 3220 , i.e. the remainder of the full division by 3220 is zero. There are infinite multiples of 3220. The smallest multiples of 3220 are:
0 : in fact, 0 is divisible by any integer, so it is also a multiple of 3220 since 0 × 3220 = 0
3220 : in fact, 3220 is a multiple of itself, since 3220 is divisible by 3220 (it was 3220 / 3220 = 1, so the rest of this division is zero)
6440: in fact, 6440 = 3220 × 2
9660: in fact, 9660 = 3220 × 3
12880: in fact, 12880 = 3220 × 4

It is possible to determine using mathematical techniques whether an integer is prime or not.
for 3220, the answer is: No, 3220 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 3220). 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 56.745 ). 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.
