Multiples of 880 are all integers divisible by 880 , i.e. the remainder of the full division by 880 is zero. There are infinite multiples of 880. The smallest multiples of 880 are:
0 : in fact, 0 is divisible by any integer, so it is also a multiple of 880 since 0 × 880 = 0
880 : in fact, 880 is a multiple of itself, since 880 is divisible by 880 (it was 880 / 880 = 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 880, the answer is: No, 880 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 880). 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 29.665 ). 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.
