The premise of your questions is false: NOT every number is a Prime number.
if you mean what three prime numbers add up to a prime number then the answer is : 5 + 7 + 11 = 23
181 is a prime number. Prime numbers can't be multiples of three.
No 5291 is not a prime using 2 numbers. It is a prime using three numbers.
no, because a composite number can be found by multiplying three prime numbers. 3*2*5 = 30, and 30 is a composite number and also has 3 prime factors. Every prime number has 1 prime factor by the way, itself. 1 is neither prime nor composite.
The sum of three odd numbers will be odd, whether they are prime or not. The sum of three prime numbers can be even as long as one of them is 2.
11, 5, 2. two is a prime number. if you don't believe me, tell me what numbers other than itself and one go into i.
11, 5 and 2 13, 3 and 2
if you mean what three prime numbers add up to a prime number then the answer is : 5 + 7 + 11 = 23
There are not three prime numbers that have the sum of 3. The smallest prime number is 2. If all three prime numbers were 2, the sum would 2 + 2 + 2 = 6, so that is the smallest number that is the sum of three prime numbers.
3, 5, and 7 are three prime numbers whose average is 5.
Prime numbers have two factors. Prime squares have three factors. Square numbers have an odd number of factors but that number varies.
3, 5, and 7 are three prime numbers whose average is 5.
7

There are no prime numbers with three factors. By definition, a prime number has exactly two factors - 1 and itself.
