Multiples of 3870 are all integers divisible by 3870 , i.e. the remainder of the full division by 3870 is zero. There are infinite multiples of 3870. The smallest multiples of 3870 are:

0 : in fact, 0 is divisible by any integer, so it is also a multiple of 3870 since 0 × 3870 = 0

3870 : in fact, 3870 is a multiple of itself, since 3870 is divisible by 3870 (it was 3870 / 3870 = 1, so the rest of this division is zero)

7740: in fact, 7740 = 3870 × 2

11610: in fact, 11610 = 3870 × 3

15480: in fact, 15480 = 3870 × 4

etc.

It is possible to determine using mathematical techniques whether an integer is prime or not.

for 3870, the answer is:
**No, 3870 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 3870). 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 62.209 ). 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.
