Multiples of 712 are all integers divisible by 712 , i.e. the remainder of the full division by 712 is zero. There are infinite multiples of 712. The smallest multiples of 712 are:

0 : in fact, 0 is divisible by any integer, so it is also a multiple of 712 since 0 × 712 = 0

712 : in fact, 712 is a multiple of itself, since 712 is divisible by 712 (it was 712 / 712 = 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 712, the answer is:
**No, 712 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 712). 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 26.683 ). 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.
