Multiples of 3200 are all integers divisible by 3200 , i.e. the remainder of the full division by 3200 is zero. There are infinite multiples of 3200. The smallest multiples of 3200 are:
0 : in fact, 0 is divisible by any integer, so it is also a multiple of 3200 since 0 × 3200 = 0
3200 : in fact, 3200 is a multiple of itself, since 3200 is divisible by 3200 (it was 3200 / 3200 = 1, so the rest of this division is zero)
6400: in fact, 6400 = 3200 × 2
9600: in fact, 9600 = 3200 × 3
12800: in fact, 12800 = 3200 × 4
16000: in fact, 16000 = 3200 × 5
etc.
It is possible to determine using mathematical techniques whether an integer is prime or not.
for 3200, the answer is: No, 3200 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 3200). 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 56.569 ). 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.
