Multiples of 897 are all integers divisible by 897 , i.e. the remainder of the full division by 897 is zero. There are infinite multiples of 897. The smallest multiples of 897 are:
0 : in fact, 0 is divisible by any integer, so it is also a multiple of 897 since 0 × 897 = 0
897 : in fact, 897 is a multiple of itself, since 897 is divisible by 897 (it was 897 / 897 = 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 897, the answer is: No, 897 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 897). 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 29.95 ). 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.
