0 : in fact, 0 is divisible by any integer, so it is also a multiple of 125 since 0 × 125 = 0

125 : in fact, 125 is a multiple of itself, since 125 is divisible by 125 (it was 125 / 125 = 1, so the rest of this division is zero)

250: in fact, 250 = 125 × 2

375: in fact, 375 = 125 × 3

500: in fact, 500 = 125 × 4

625: in fact, 625 = 125 × 5

etc.

## Is 125 a prime number?

It is possible to determine using mathematical techniques whether an integer is prime or not.

for 125, the answer is: No, 125 is not a prime number.

## 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 125). 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 11.18 ). 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.
