## What are the multiples of 24?

Multiples of 24 are all integers divisible by 24 , i.e. the remainder of the full division by 24 is zero. There are infinite multiples of 24. The smallest multiples of 24 are:

0 : in fact, 0 is divisible by any integer, so it is also a multiple of 24 since 0 × 24 = 0

24 : in fact, 24 is a multiple of itself, since 24 is divisible by 24 (it was 24 / 24 = 1, so the rest of this division is zero)

48: in fact, 48 = 24 × 2

72: in fact, 72 = 24 × 3

96: in fact, 96 = 24 × 4

120: in fact, 120 = 24 × 5

etc.

## Is 24 a prime number?

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

for 24, the answer is: No, 24 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 24). 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 4.899 ). 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.
