Multiples of 1100 are all integers divisible by 1100 , i.e. the remainder of the full division by 1100 is zero. There are infinite multiples of 1100. The smallest multiples of 1100 are:
0 : in fact, 0 is divisible by any integer, so it is also a multiple of 1100 since 0 × 1100 = 0
1100 : in fact, 1100 is a multiple of itself, since 1100 is divisible by 1100 (it was 1100 / 1100 = 1, so the rest of this division is zero)
2200: in fact, 2200 = 1100 × 2
3300: in fact, 3300 = 1100 × 3
4400: in fact, 4400 = 1100 × 4
5500: in fact, 5500 = 1100 × 5
etc.
It is possible to determine using mathematical techniques whether an integer is prime or not.
for 1100, the answer is: No, 1100 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 1100). 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 33.166 ). 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.
