Multiples of 6500 are all integers divisible by 6500 , i.e. the remainder of the full division by 6500 is zero. There are infinite multiples of 6500. The smallest multiples of 6500 are:
0 : in fact, 0 is divisible by any integer, so it is also a multiple of 6500 since 0 × 6500 = 0
6500 : in fact, 6500 is a multiple of itself, since 6500 is divisible by 6500 (it was 6500 / 6500 = 1, so the rest of this division is zero)
13000: in fact, 13000 = 6500 × 2
19500: in fact, 19500 = 6500 × 3
26000: in fact, 26000 = 6500 × 4

etc.
It is possible to determine using mathematical techniques whether an integer is prime or not.
for 6500, the answer is: No, 6500 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 6500). 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 80.623 ). 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.
