Multiples of 940 are all integers divisible by 940 , i.e. the remainder of the full division by 940 is zero. There are infinite multiples of 940. The smallest multiples of 940 are:
0 : in fact, 0 is divisible by any integer, so it is also a multiple of 940 since 0 × 940 = 0
940 : in fact, 940 is a multiple of itself, since 940 is divisible by 940 (it was 940 / 940 = 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 940, the answer is: No, 940 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 940). 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 30.659 ). 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.
