Multiples of 975 are all integers divisible by 975 , i.e. the remainder of the full division by 975 is zero. There are infinite multiples of 975. The smallest multiples of 975 are:
0 : in fact, 0 is divisible by any integer, so it is also a multiple of 975 since 0 × 975 = 0
975 : in fact, 975 is a multiple of itself, since 975 is divisible by 975 (it was 975 / 975 = 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 975, the answer is: No, 975 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 975). 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 31.225 ). 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.
