0 : in fact, 0 is divisible by any integer, so it is also a multiple of 2025 since 0 × 2025 = 0
2025 : in fact, 2025 is a multiple of itself, since 2025 is divisible by 2025 (it was 2025 / 2025 = 1, so the rest of this division is zero)
4050: in fact, 4050 = 2025 × 2
6075: in fact, 6075 = 2025 × 3

etc.
It is possible to determine using mathematical techniques whether an integer is prime or not.
for 2025, the answer is: No, 2025 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 2025). 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 45 ). 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.
