Multiples of 200 are all integers divisible by 200 , i.e. the remainder of the full division by 200 is zero. There are infinite multiples of 200. The smallest multiples of 200 are:
0 : in fact, 0 is divisible by any integer, so it is also a multiple of 200 since 0 × 200 = 0
200 : in fact, 200 is a multiple of itself, since 200 is divisible by 200 (it was 200 / 200 = 1, so the rest of this division is zero)
etc.
It is possible to determine using mathematical techniques whether an integer is prime or not.
for 200, the answer is: No, 200 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 200). 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 14.142 ). 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.
