Multiples of 80000 are all integers divisible by 80000 , i.e. the remainder of the full division by 80000 is zero. There are infinite multiples of 80000. The smallest multiples of 80000 are:
0 : in fact, 0 is divisible by any integer, so it is also a multiple of 80000 since 0 × 80000 = 0
80000 : in fact, 80000 is a multiple of itself, since 80000 is divisible by 80000 (it was 80000 / 80000 = 1, so the rest of this division is zero)
160000: in fact, 160000 = 80000 × 2
240000: in fact, 240000 = 80000 × 3

It is possible to determine using mathematical techniques whether an integer is prime or not.
for 80000, the answer is: No, 80000 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 80000). 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 282.843 ). 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.
