What are the multiples of 225?
Multiples of 225 are all integers divisible by 225 , i.e. the remainder of the full division by 225 is zero. There are infinite multiples of 225. The smallest multiples of 225 are:
0 : in fact, 0 is divisible by any integer, so it is also a multiple of 225 since 0 × 225 = 0
225 : in fact, 225 is a multiple of itself, since 225 is divisible by 225 (it was 225 / 225 = 1, so the rest of this division is zero)
etc.
Is 225 a prime number?
It is possible to determine using mathematical techniques whether an integer is prime or not.
for 225, the answer is: No, 225 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 225). 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 ). 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.
