Multiples of 2800 are all integers divisible by 2800 , i.e. the remainder of the full division by 2800 is zero. There are infinite multiples of 2800. The smallest multiples of 2800 are:
0 : in fact, 0 is divisible by any integer, so it is also a multiple of 2800 since 0 × 2800 = 0
2800 : in fact, 2800 is a multiple of itself, since 2800 is divisible by 2800 (it was 2800 / 2800 = 1, so the rest of this division is zero)
5600: in fact, 5600 = 2800 × 2
8400: in fact, 8400 = 2800 × 3
11200: in fact, 11200 = 2800 × 4
14000: in fact, 14000 = 2800 × 5
etc.
It is possible to determine using mathematical techniques whether an integer is prime or not.
for 2800, the answer is: No, 2800 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 2800). 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 52.915 ). 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.
