Since 730 divided by -2 is a whole number, -2 is a factor of 730
Since 730 divided by -1 is a whole number, -1 is a factor of 730
Multiples of 730 are all integers divisible by 730 , i.e. the remainder of the full division by 730 is zero. There are infinite multiples of 730. The smallest multiples of 730 are:
It is possible to determine using mathematical techniques whether an integer is prime or not.
for 730, the answer is: No, 730 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 730). 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 27.019 ). 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.
