The list of **all positive divisors** (that is, the list of all integers that **divide 22**) is as follows :

Accordingly:

**676** is multiplo of **1**

**676** is multiplo of **2**

**676** is multiplo of **4**

**676** is multiplo of **13**

**676** is multiplo of **26**

**676** is multiplo of **52**

**676** is multiplo of **169**

**676** is multiplo of **338**

**676** has **8 positive divisors **

In addition we can say of the number **676 that it is even**

676 is an even number, as it is divisible by 2 : 676/2 = 338

Multiples of 676 are all integers divisible by 676 , i.e. the remainder of the full division by 676 is zero. There are infinite multiples of 676. The smallest multiples of 676 are:

0 : in fact, 0 is divisible by any integer, so it is also a multiple of 676 since 0 × 676 = 0

676 : in fact, 676 is a multiple of itself, since 676 is divisible by 676 (it was 676 / 676 = 1, so the rest of this division is zero)

etc.

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

for 676, the answer is:
**No, 676 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 676). 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 26 ). 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.
