Since 470 divided by -2 is a whole number, -2 is a factor of 470
Since 470 divided by -1 is a whole number, -1 is a factor of 470
Multiples of 470 are all integers divisible by 470 , i.e. the remainder of the full division by 470 is zero. There are infinite multiples of 470. The smallest multiples of 470 are:
It is possible to determine using mathematical techniques whether an integer is prime or not.
for 470, the answer is: No, 470 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 470). 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 21.679 ). 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.
