Multiples of 112 are all integers divisible by 112 , i.e. the remainder of the full division by 112 is zero. There are infinite multiples of 112. The smallest multiples of 112 are:
0 : in fact, 0 is divisible by any integer, so it is also a multiple of 112 since 0 × 112 = 0
112 : in fact, 112 is a multiple of itself, since 112 is divisible by 112 (it was 112 / 112 = 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 112, the answer is: No, 112 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 112). 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 10.583 ). 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.
