37is an odd number,as it is not divisible by 2
The factors for 37 are all the numbers between -37 and 37 , which divide 37 without leaving any remainder. Since 37 divided by -37 is an integer, -37 is a factor of 37 .
Since 37 divided by -37 is a whole number, -37 is a factor of 37
Since 37 divided by -1 is a whole number, -1 is a factor of 37
Multiples of 37 are all integers divisible by 37 , i.e. the remainder of the full division by 37 is zero. There are infinite multiples of 37. The smallest multiples of 37 are:
It is possible to determine using mathematical techniques whether an integer is prime or not.
for 37, the answer is: yes, 37 is a prime number because it only has two different divisors: 1 and itself (37).
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 37). 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 6.083 ). 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.
