5101is an odd number,as it is not divisible by 2
The factors for 5101 are all the numbers between -5101 and 5101 , which divide 5101 without leaving any remainder. Since 5101 divided by -5101 is an integer, -5101 is a factor of 5101 .
Since 5101 divided by -5101 is a whole number, -5101 is a factor of 5101
Since 5101 divided by -1 is a whole number, -1 is a factor of 5101
Since 5101 divided by 1 is a whole number, 1 is a factor of 5101
Multiples of 5101 are all integers divisible by 5101 , i.e. the remainder of the full division by 5101 is zero. There are infinite multiples of 5101. The smallest multiples of 5101 are:
0 : in fact, 0 is divisible by any integer, so it is also a multiple of 5101 since 0 × 5101 = 0
5101 : in fact, 5101 is a multiple of itself, since 5101 is divisible by 5101 (it was 5101 / 5101 = 1, so the rest of this division is zero)
10202: in fact, 10202 = 5101 × 2
15303: in fact, 15303 = 5101 × 3
20404: in fact, 20404 = 5101 × 4
25505: in fact, 25505 = 5101 × 5
etc.
It is possible to determine using mathematical techniques whether an integer is prime or not.
for 5101, the answer is: yes, 5101 is a prime number because it only has two different divisors: 1 and itself (5101).
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 5101). 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 71.421 ). 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.
