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

Accordingly:

**196** is multiplo of **1**

**196** is multiplo of **2**

**196** is multiplo of **4**

**196** is multiplo of **7**

**196** is multiplo of **14**

**196** is multiplo of **28**

**196** is multiplo of **49**

**196** is multiplo of **98**

**196** has **8 positive divisors **

In addition we can say of the number **196 that it is even**

196 is an even number, as it is divisible by 2 : 196/2 = 98

The factors for 196 are all the numbers between -196 and 196 , which divide 196 without leaving any remainder. Since 196 divided by -196 is an integer, -196 is a factor of 196 .

Since 196 divided by -196 is a whole number, -196 is a factor of 196

Since 196 divided by -98 is a whole number, -98 is a factor of 196

Since 196 divided by -49 is a whole number, -49 is a factor of 196

Since 196 divided by -28 is a whole number, -28 is a factor of 196

Since 196 divided by -14 is a whole number, -14 is a factor of 196

Since 196 divided by -7 is a whole number, -7 is a factor of 196

Since 196 divided by -4 is a whole number, -4 is a factor of 196

Since 196 divided by -2 is a whole number, -2 is a factor of 196

Since 196 divided by -1 is a whole number, -1 is a factor of 196

Since 196 divided by 1 is a whole number, 1 is a factor of 196

Since 196 divided by 2 is a whole number, 2 is a factor of 196

Since 196 divided by 4 is a whole number, 4 is a factor of 196

Since 196 divided by 7 is a whole number, 7 is a factor of 196

Since 196 divided by 14 is a whole number, 14 is a factor of 196

Since 196 divided by 28 is a whole number, 28 is a factor of 196

Since 196 divided by 49 is a whole number, 49 is a factor of 196

Since 196 divided by 98 is a whole number, 98 is a factor of 196

Multiples of 196 are all integers divisible by 196 , i.e. the remainder of the full division by 196 is zero. There are infinite multiples of 196. The smallest multiples of 196 are:

0 : in fact, 0 is divisible by any integer, so it is also a multiple of 196 since 0 × 196 = 0

196 : in fact, 196 is a multiple of itself, since 196 is divisible by 196 (it was 196 / 196 = 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 196, the answer is:
**No, 196 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 196). 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 ). 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.
