Multiples of 496 are all integers divisible by 496 , i.e. the remainder of the full division by 496 is zero. There are infinite multiples of 496. The smallest multiples of 496 are:
0 : in fact, 0 is divisible by any integer, so it is also a multiple of 496 since 0 × 496 = 0
496 : in fact, 496 is a multiple of itself, since 496 is divisible by 496 (it was 496 / 496 = 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 496, the answer is: No, 496 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 496). 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 22.271 ). 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.
