237is an odd number,as it is not divisible by 2
The factors for 237 are all the numbers between -237 and 237 , which divide 237 without leaving any remainder. Since 237 divided by -237 is an integer, -237 is a factor of 237 .
Since 237 divided by -237 is a whole number, -237 is a factor of 237
Since 237 divided by -79 is a whole number, -79 is a factor of 237
Since 237 divided by -3 is a whole number, -3 is a factor of 237
Since 237 divided by -1 is a whole number, -1 is a factor of 237
Multiples of 237 are all integers divisible by 237 , i.e. the remainder of the full division by 237 is zero. There are infinite multiples of 237. The smallest multiples of 237 are:
It is possible to determine using mathematical techniques whether an integer is prime or not.
for 237, the answer is: No, 237 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 237). 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 15.395 ). 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.
