Multiples of 544 are all integers divisible by 544 , i.e. the remainder of the full division by 544 is zero. There are infinite multiples of 544. The smallest multiples of 544 are:
0 : in fact, 0 is divisible by any integer, so it is also a multiple of 544 since 0 × 544 = 0
544 : in fact, 544 is a multiple of itself, since 544 is divisible by 544 (it was 544 / 544 = 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 544, the answer is: No, 544 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 544). 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 23.324 ). 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.
