379is an odd number,as it is not divisible by 2
The factors for 379 are all the numbers between -379 and 379 , which divide 379 without leaving any remainder. Since 379 divided by -379 is an integer, -379 is a factor of 379 .
Since 379 divided by -379 is a whole number, -379 is a factor of 379
Since 379 divided by -1 is a whole number, -1 is a factor of 379
Since 379 divided by 1 is a whole number, 1 is a factor of 379
Multiples of 379 are all integers divisible by 379 , i.e. the remainder of the full division by 379 is zero. There are infinite multiples of 379. The smallest multiples of 379 are:
0 : in fact, 0 is divisible by any integer, so it is also a multiple of 379 since 0 × 379 = 0
379 : in fact, 379 is a multiple of itself, since 379 is divisible by 379 (it was 379 / 379 = 1, so the rest of this division is zero)
It is possible to determine using mathematical techniques whether an integer is prime or not.
for 379, the answer is: yes, 379 is a prime number because it only has two different divisors: 1 and itself (379).
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 379). 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 19.468 ). 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.
