80051is an odd number,as it is not divisible by 2
The factors for 80051 are all the numbers between -80051 and 80051 , which divide 80051 without leaving any remainder. Since 80051 divided by -80051 is an integer, -80051 is a factor of 80051 .
Since 80051 divided by -80051 is a whole number, -80051 is a factor of 80051
Since 80051 divided by -1 is a whole number, -1 is a factor of 80051
Since 80051 divided by 1 is a whole number, 1 is a factor of 80051
Multiples of 80051 are all integers divisible by 80051 , i.e. the remainder of the full division by 80051 is zero. There are infinite multiples of 80051. The smallest multiples of 80051 are:
0 : in fact, 0 is divisible by any integer, so it is also a multiple of 80051 since 0 × 80051 = 0
80051 : in fact, 80051 is a multiple of itself, since 80051 is divisible by 80051 (it was 80051 / 80051 = 1, so the rest of this division is zero)
160102: in fact, 160102 = 80051 × 2
240153: in fact, 240153 = 80051 × 3
320204: in fact, 320204 = 80051 × 4

It is possible to determine using mathematical techniques whether an integer is prime or not.
for 80051, the answer is: yes, 80051 is a prime number because it only has two different divisors: 1 and itself (80051).
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 80051). 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 282.933 ). 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.
