Multiples of 836 are all integers divisible by 836 , i.e. the remainder of the full division by 836 is zero. There are infinite multiples of 836. The smallest multiples of 836 are:
0 : in fact, 0 is divisible by any integer, so it is also a multiple of 836 since 0 × 836 = 0
836 : in fact, 836 is a multiple of itself, since 836 is divisible by 836 (it was 836 / 836 = 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 836, the answer is: No, 836 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 836). 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 28.914 ). 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.
