What are the multiples of 441?
Multiples of 441 are all integers divisible by 441 , i.e. the remainder of the full division by 441 is zero. There are infinite multiples of 441. The smallest multiples of 441 are:
0 : in fact, 0 is divisible by any integer, so it is also a multiple of 441 since 0 × 441 = 0
441 : in fact, 441 is a multiple of itself, since 441 is divisible by 441 (it was 441 / 441 = 1, so the rest of this division is zero)
etc.
Is 441 a prime number?
It is possible to determine using mathematical techniques whether an integer is prime or not.
for 441, the answer is: No, 441 is not a prime number.
How do you determine if a number is prime?
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 441). 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 ). 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.
