Since 246 divided by -2 is a whole number, -2 is a factor of 246
Since 246 divided by -1 is a whole number, -1 is a factor of 246
Multiples of 246 are all integers divisible by 246 , i.e. the remainder of the full division by 246 is zero. There are infinite multiples of 246. The smallest multiples of 246 are:
It is possible to determine using mathematical techniques whether an integer is prime or not.
for 246, the answer is: No, 246 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 246). 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 15.684 ). 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.
