Multiples of 888 are all integers divisible by 888 , i.e. the remainder of the full division by 888 is zero. There are infinite multiples of 888. The smallest multiples of 888 are:
0 : in fact, 0 is divisible by any integer, so it is also a multiple of 888 since 0 × 888 = 0
888 : in fact, 888 is a multiple of itself, since 888 is divisible by 888 (it was 888 / 888 = 1, so the rest of this division is zero)
etc.
It is possible to determine using mathematical techniques whether an integer is prime or not.
for 888, the answer is: No, 888 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 888). 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 29.799 ). 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.
