Multiples of 726 are all integers divisible by 726 , i.e. the remainder of the full division by 726 is zero. There are infinite multiples of 726. The smallest multiples of 726 are:
0 : in fact, 0 is divisible by any integer, so it is also a multiple of 726 since 0 × 726 = 0
726 : in fact, 726 is a multiple of itself, since 726 is divisible by 726 (it was 726 / 726 = 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 726, the answer is: No, 726 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 726). 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 26.944 ). 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.
