What is the sum of the first four prime number

Sagot :

The first four prime numbers are:  2, 3, 5, and 7

Add:
2 + 3 + 5 + 7 = 17  (which is also a prime number)

ANSWER:  The sum of the first four prime numbers is 17.

Note:  1 is not a prime number because, by definition, a prime number is a number greater than 1 that has no other positive integers other than itself and 1.  Therefore, it has EXACTLY TWO positive divisors.

**NOTE: Integers greater than one are called a prime number if its only positive divisors (factors) are one and itself. Therefore, 1 isn't a prime number and you must remember that :) . **

The first four prime numbers are 2, 3, 5 and 7.

2 + 3 + 5 + 7 = 17

ANSWER: 17.
