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:
0 : in fact, 0 is divisible by any integer, so it is also a multiple of 277 since 0 × 277 = 0
277 : in fact, 277 is a multiple of itself, since 277 is divisible by 277 (it was 277 / 277 = 1, so the rest of this division is zero)
etc.
Is 277 a prime number?
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).
How do you determine if a number is prime?
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.
