Multiples of 36 are all integers divisible by 36 , i.e. the remainder of the full division by 36 is zero. There are infinite multiples of 36. The smallest multiples of 36 are:
0 : in fact, 0 is divisible by any integer, so it is also a multiple of 36 since 0 × 36 = 0
36 : in fact, 36 is a multiple of itself, since 36 is divisible by 36 (it was 36 / 36 = 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 36, the answer is: No, 36 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 36). 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 6 ). 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.
