Multiples of 774 are all integers divisible by 774 , i.e. the remainder of the full division by 774 is zero. There are infinite multiples of 774. The smallest multiples of 774 are:
0 : in fact, 0 is divisible by any integer, so it is also a multiple of 774 since 0 × 774 = 0
774 : in fact, 774 is a multiple of itself, since 774 is divisible by 774 (it was 774 / 774 = 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 774, the answer is: No, 774 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 774). 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 27.821 ). 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.
