Multiples of 980 are all integers divisible by 980 , i.e. the remainder of the full division by 980 is zero. There are infinite multiples of 980. The smallest multiples of 980 are:
0 : in fact, 0 is divisible by any integer, so it is also a multiple of 980 since 0 × 980 = 0
980 : in fact, 980 is a multiple of itself, since 980 is divisible by 980 (it was 980 / 980 = 1, so the rest of this division is zero)
etc.
It is possible to determine using mathematical techniques whether an integer is prime or not.
for 980, the answer is: No, 980 is not a prime number.
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 980). 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 31.305 ). 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.
