Multiples of 1877 are all integers divisible by 1877 , i.e. the remainder of the full division by 1877 is zero. There are infinite multiples of 1877. The smallest multiples of 1877 are:
0 : in fact, 0 is divisible by any integer, so it is also a multiple of 1877 since 0 × 1877 = 0
1877 : in fact, 1877 is a multiple of itself, since 1877 is divisible by 1877 (it was 1877 / 1877 = 1, so the rest of this division is zero)
3754: in fact, 3754 = 1877 × 2
5631: in fact, 5631 = 1877 × 3

etc.
It is possible to determine using mathematical techniques whether an integer is prime or not.
for 1877, the answer is: yes, 1877 is a prime number because it only has two different divisors: 1 and itself (1877).
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 1877). 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 43.324 ). 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.
