Multiples of 276 are all integers divisible by 276 , i.e. the remainder of the full division by 276 is zero. There are infinite multiples of 276. The smallest multiples of 276 are:
0 : in fact, 0 is divisible by any integer, so it is also a multiple of 276 since 0 × 276 = 0
276 : in fact, 276 is a multiple of itself, since 276 is divisible by 276 (it was 276 / 276 = 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 276, the answer is: No, 276 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 276). 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 16.613 ). 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.
