Multiples of 152 are all integers divisible by 152 , i.e. the remainder of the full division by 152 is zero. There are infinite multiples of 152. The smallest multiples of 152 are:

0 : in fact, 0 is divisible by any integer, so it is also a multiple of 152 since 0 × 152 = 0

152 : in fact, 152 is a multiple of itself, since 152 is divisible by 152 (it was 152 / 152 = 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 152, the answer is:
**No, 152 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 152). 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 12.329 ). 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.
