0 : in fact, 0 is divisible by any integer, so it is also a multiple of 2001 since 0 × 2001 = 0
2001 : in fact, 2001 is a multiple of itself, since 2001 is divisible by 2001 (it was 2001 / 2001 = 1, so the rest of this division is zero)
4002: in fact, 4002 = 2001 × 2
6003: in fact, 6003 = 2001 × 3
8004: in fact, 8004 = 2001 × 4
10005: in fact, 10005 = 2001 × 5
etc.
Is 2001 a prime number?
It is possible to determine using mathematical techniques whether an integer is prime or not.
for 2001, the answer is: No, 2001 is not a prime number.
How do you determine if a number is prime?
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 2001). 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 44.733 ). 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.
