## What are the multiples of 220?

Multiples of 220 are all integers divisible by 220 , i.e. the remainder of the full division by 220 is zero. There are infinite multiples of 220. The smallest multiples of 220 are:

0 : in fact, 0 is divisible by any integer, so it is also a multiple of 220 since 0 × 220 = 0

220 : in fact, 220 is a multiple of itself, since 220 is divisible by 220 (it was 220 / 220 = 1, so the rest of this division is zero)

440: in fact, 440 = 220 × 2

660: in fact, 660 = 220 × 3

880: in fact, 880 = 220 × 4

1100: in fact, 1100 = 220 × 5

etc.

## Is 220 a prime number?

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

for 220, the answer is: No, 220 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 220). 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 14.832 ). 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.
