Multiples of 456 are all integers divisible by 456 , i.e. the remainder of the full division by 456 is zero. There are infinite multiples of 456. The smallest multiples of 456 are:
0 : in fact, 0 is divisible by any integer, so it is also a multiple of 456 since 0 × 456 = 0
456 : in fact, 456 is a multiple of itself, since 456 is divisible by 456 (it was 456 / 456 = 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 456, the answer is: No, 456 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 456). 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 21.354 ). 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.
