277is an odd number,as it is not divisible by 2
The factors for 277 are all the numbers between -277 and 277 , which divide 277 without leaving any remainder. Since 277 divided by -277 is an integer, -277 is a factor of 277 .
Since 277 divided by -277 is a whole number, -277 is a factor of 277
Since 277 divided by -1 is a whole number, -1 is a factor of 277
Multiples of 277 are all integers divisible by 277 , i.e. the remainder of the full division by 277 is zero. There are infinite multiples of 277. The smallest multiples of 277 are:
It is possible to determine using mathematical techniques whether an integer is prime or not.
for 277, the answer is: yes, 277 is a prime number because it only has two different divisors: 1 and itself (277).
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 277). 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 16.643 ). 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.
