0 : in fact, 0 is divisible by any integer, so it is also a multiple of 5051 since 0 × 5051 = 0
5051 : in fact, 5051 is a multiple of itself, since 5051 is divisible by 5051 (it was 5051 / 5051 = 1, so the rest of this division is zero)
10102: in fact, 10102 = 5051 × 2
15153: in fact, 15153 = 5051 × 3
20204: in fact, 20204 = 5051 × 4
25255: in fact, 25255 = 5051 × 5
etc.
It is possible to determine using mathematical techniques whether an integer is prime or not.
for 5051, the answer is: yes, 5051 is a prime number because it only has two different divisors: 1 and itself (5051).
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 5051). 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 71.07 ). 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.
