Multiples of 472 are all integers divisible by 472 , i.e. the remainder of the full division by 472 is zero. There are infinite multiples of 472. The smallest multiples of 472 are:
It is possible to determine using mathematical techniques whether an integer is prime or not.
for 472, the answer is: No, 472 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 472). 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 21.726 ). 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.
