5011is an odd number,as it is not divisible by 2
The factors for 5011 are all the numbers between -5011 and 5011 , which divide 5011 without leaving any remainder. Since 5011 divided by -5011 is an integer, -5011 is a factor of 5011 .
Since 5011 divided by -5011 is a whole number, -5011 is a factor of 5011
Since 5011 divided by -1 is a whole number, -1 is a factor of 5011
Since 5011 divided by 1 is a whole number, 1 is a factor of 5011
Multiples of 5011 are all integers divisible by 5011 , i.e. the remainder of the full division by 5011 is zero. There are infinite multiples of 5011. The smallest multiples of 5011 are:
0 : in fact, 0 is divisible by any integer, so it is also a multiple of 5011 since 0 × 5011 = 0
5011 : in fact, 5011 is a multiple of itself, since 5011 is divisible by 5011 (it was 5011 / 5011 = 1, so the rest of this division is zero)
10022: in fact, 10022 = 5011 × 2
15033: in fact, 15033 = 5011 × 3
20044: in fact, 20044 = 5011 × 4
25055: in fact, 25055 = 5011 × 5
etc.
It is possible to determine using mathematical techniques whether an integer is prime or not.
for 5011, the answer is: yes, 5011 is a prime number because it only has two different divisors: 1 and itself (5011).
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 5011). 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 70.788 ). 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.
