Multiples of 500000 are all integers divisible by 500000 , i.e. the remainder of the full division by 500000 is zero. There are infinite multiples of 500000. The smallest multiples of 500000 are:
0 : in fact, 0 is divisible by any integer, so it is also a multiple of 500000 since 0 × 500000 = 0
500000 : in fact, 500000 is a multiple of itself, since 500000 is divisible by 500000 (it was 500000 / 500000 = 1, so the rest of this division is zero)
1000000: in fact, 1000000 = 500000 × 2
1500000: in fact, 1500000 = 500000 × 3

etc.
It is possible to determine using mathematical techniques whether an integer is prime or not.
for 500000, the answer is: No, 500000 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 500000). 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 707.107 ). 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.
