497is an odd number,as it is not divisible by 2
The factors for 497 are all the numbers between -497 and 497 , which divide 497 without leaving any remainder. Since 497 divided by -497 is an integer, -497 is a factor of 497 .
Since 497 divided by -497 is a whole number, -497 is a factor of 497
Since 497 divided by -71 is a whole number, -71 is a factor of 497
Since 497 divided by -7 is a whole number, -7 is a factor of 497
Since 497 divided by -1 is a whole number, -1 is a factor of 497
Since 497 divided by 1 is a whole number, 1 is a factor of 497
Since 497 divided by 7 is a whole number, 7 is a factor of 497
Since 497 divided by 71 is a whole number, 71 is a factor of 497
Multiples of 497 are all integers divisible by 497 , i.e. the remainder of the full division by 497 is zero. There are infinite multiples of 497. The smallest multiples of 497 are:
0 : in fact, 0 is divisible by any integer, so it is also a multiple of 497 since 0 × 497 = 0
497 : in fact, 497 is a multiple of itself, since 497 is divisible by 497 (it was 497 / 497 = 1, so the rest of this division is zero)
etc.
It is possible to determine using mathematical techniques whether an integer is prime or not.
for 497, the answer is: No, 497 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 497). 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 22.293 ). 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.
