What are the multiples of 16?

Multiples of 16 are all integers divisible by 16 , i.e. the remainder of the full division by 16 is zero. There are infinite multiples of 16. The smallest multiples of 16 are:

0 : in fact, 0 is divisible by any integer, so it is also a multiple of 16 since 0 × 16 = 0

16 : in fact, 16 is a multiple of itself, since 16 is divisible by 16 (it was 16 / 16 = 1, so the rest of this division is zero)

32: in fact, 32 = 16 × 2

48: in fact, 48 = 16 × 3

64: in fact, 64 = 16 × 4

80: in fact, 80 = 16 × 5

etc.

Is 16 a prime number?

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

for 16, the answer is: No, 16 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 16). 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 ). 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.
