Multiples of 2100 are all integers divisible by 2100 , i.e. the remainder of the full division by 2100 is zero. There are infinite multiples of 2100. The smallest multiples of 2100 are:
0 : in fact, 0 is divisible by any integer, so it is also a multiple of 2100 since 0 × 2100 = 0
2100 : in fact, 2100 is a multiple of itself, since 2100 is divisible by 2100 (it was 2100 / 2100 = 1, so the rest of this division is zero)
4200: in fact, 4200 = 2100 × 2
6300: in fact, 6300 = 2100 × 3
8400: in fact, 8400 = 2100 × 4
10500: in fact, 10500 = 2100 × 5
etc.
It is possible to determine using mathematical techniques whether an integer is prime or not.
for 2100, the answer is: No, 2100 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 2100). 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 45.826 ). 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.
