Multiples of 3800 are all integers divisible by 3800 , i.e. the remainder of the full division by 3800 is zero. There are infinite multiples of 3800. The smallest multiples of 3800 are:
0 : in fact, 0 is divisible by any integer, so it is also a multiple of 3800 since 0 × 3800 = 0
3800 : in fact, 3800 is a multiple of itself, since 3800 is divisible by 3800 (it was 3800 / 3800 = 1, so the rest of this division is zero)
7600: in fact, 7600 = 3800 × 2
11400: in fact, 11400 = 3800 × 3
15200: in fact, 15200 = 3800 × 4

etc.
It is possible to determine using mathematical techniques whether an integer is prime or not.
for 3800, the answer is: No, 3800 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 3800). 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 61.644 ). 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.
