Multiples of 855 are all integers divisible by 855 , i.e. the remainder of the full division by 855 is zero. There are infinite multiples of 855. The smallest multiples of 855 are:
0 : in fact, 0 is divisible by any integer, so it is also a multiple of 855 since 0 × 855 = 0
855 : in fact, 855 is a multiple of itself, since 855 is divisible by 855 (it was 855 / 855 = 1, so the rest of this division is zero)
etc.
Is 855 a prime number?
It is possible to determine using mathematical techniques whether an integer is prime or not.
for 855, the answer is: No, 855 is not a prime number.
How do you determine if a number is prime?
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 855). 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 29.24 ). 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.
