Multiples of 156 are all integers divisible by 156 , i.e. the remainder of the full division by 156 is zero. There are infinite multiples of 156. The smallest multiples of 156 are:

0 : in fact, 0 is divisible by any integer, so it is also a multiple of 156 since 0 × 156 = 0

156 : in fact, 156 is a multiple of itself, since 156 is divisible by 156 (it was 156 / 156 = 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 156, the answer is:
**No, 156 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 156). 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 12.49 ). 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.
