## What are the multiples of 100?

Multiples of 100 are all integers divisible by 100 , i.e. the remainder of the full division by 100 is zero. There are infinite multiples of 100. The smallest multiples of 100 are:

0 : in fact, 0 is divisible by any integer, so it is also a multiple of 100 since 0 × 100 = 0

100 : in fact, 100 is a multiple of itself, since 100 is divisible by 100 (it was 100 / 100 = 1, so the rest of this division is zero)

200: in fact, 200 = 100 × 2

300: in fact, 300 = 100 × 3

400: in fact, 400 = 100 × 4

500: in fact, 500 = 100 × 5

etc.

## Is 100 a prime number?

It is possible to determine using mathematical techniques whether an integer is prime or not.

for 100, the answer is: No, 100 is not a prime number.

## How do you determine if a number is prime?

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 100). 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 ). 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.
