877is an odd number,as it is not divisible by 2
The factors for 877 are all the numbers between -877 and 877 , which divide 877 without leaving any remainder. Since 877 divided by -877 is an integer, -877 is a factor of 877 .
Since 877 divided by -877 is a whole number, -877 is a factor of 877
Since 877 divided by -1 is a whole number, -1 is a factor of 877
Multiples of 877 are all integers divisible by 877 , i.e. the remainder of the full division by 877 is zero. There are infinite multiples of 877. The smallest multiples of 877 are:
It is possible to determine using mathematical techniques whether an integer is prime or not.
for 877, the answer is: yes, 877 is a prime number because it only has two different divisors: 1 and itself (877).
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 877). 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 29.614 ). 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.
