0 : in fact, 0 is divisible by any integer, so it is also a multiple of 20000 since 0 × 20000 = 0
20000 : in fact, 20000 is a multiple of itself, since 20000 is divisible by 20000 (it was 20000 / 20000 = 1, so the rest of this division is zero)
40000: in fact, 40000 = 20000 × 2
60000: in fact, 60000 = 20000 × 3

It is possible to determine using mathematical techniques whether an integer is prime or not.
for 20000, the answer is: No, 20000 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 20000). 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 141.421 ). 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.
