Multiples of 889 are all integers divisible by 889 , i.e. the remainder of the full division by 889 is zero. There are infinite multiples of 889. The smallest multiples of 889 are:
0 : in fact, 0 is divisible by any integer, so it is also a multiple of 889 since 0 × 889 = 0
889 : in fact, 889 is a multiple of itself, since 889 is divisible by 889 (it was 889 / 889 = 1, so the rest of this division is zero)
It is possible to determine using mathematical techniques whether an integer is prime or not.
for 889, the answer is: No, 889 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 889). 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 29.816 ). 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.
