Multiples of 446 are all integers divisible by 446 , i.e. the remainder of the full division by 446 is zero. There are infinite multiples of 446. The smallest multiples of 446 are:
0 : in fact, 0 is divisible by any integer, so it is also a multiple of 446 since 0 × 446 = 0
446 : in fact, 446 is a multiple of itself, since 446 is divisible by 446 (it was 446 / 446 = 1, so the rest of this division is zero)
It is possible to determine using mathematical techniques whether an integer is prime or not.
for 446, the answer is: No, 446 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 446). 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 21.119 ). 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.
