Multiples of 434 are all integers divisible by 434 , i.e. the remainder of the full division by 434 is zero. There are infinite multiples of 434. The smallest multiples of 434 are:
It is possible to determine using mathematical techniques whether an integer is prime or not.
for 434, the answer is: No, 434 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 434). 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 20.833 ). 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.
