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.
The sum of the first prime numbers is 5 Because the first prime numbers are 2 & 3. Thus , 2 + 3 =5 The sum is 5 I hope you understand my reason for my answer. By grade 4 th student byeee
The sum of two prime numbers greater than 2 is an even number. The sum of 2 and any other prime number is an odd number.
Prime factors of 78 are: 2, 3 and 13
The sum of any two prime numbers may or may not be prime. The sum of the two prime numbers 2 and 3 is the prime number 5, and the sum of the two prime numbers 5 and 7 is the composite number 12.
The sum of the two prime numbers 3 and 73 is 76.
It is impossible for the product of two prime numbers to be prime. It is impossible for the sum of two prime numbers to be prime as long as one of the numbers isn't 2.
The sum of two prime numbers will be composite unless one of the prime numbers is 2.
If one of the two numbers is 2, the sum of two prime numbers may sometimes be a prime number. Examples of this are 2 + 11 = 13, 2 + 521 = 523, 2 + 281 = 283. There are an infinite number of similar examples where the sum of 2 plus a prime is another prime. However if neither number is 2, then the sum of two prime numbers is always an even number greater than 2 and therefore composite.
Some odd numbers can be written as the sum of prime numbers. 2 + 3 = 5
The prime factorization of 36 is 2 x 2 x 3 x 3. The sum of the prime numbers 2 and 3 is 5.
The sum of any pair of prime numbers greater than 2 is an even number.
For a 2-digit prime number (which are all odd) to be the sum of two prime numbers, one of the prime numbers will have to be 2. That means the difference between the sum and the other addend will have to be 2. Prime numbers that differ by 2 are called twin primes. There are six pairs of 2-digit twin primes. Your numbers are 13, 19, 31, 43, 61 and 73.
No. The sum of two odd numbers is always even, and no prime is even (apart from 2, but it is the lowest prime, so no primes can be added to form it).
Prime numbers less than 10 = 2, 3, 5, 7The sum of prime numbers less than 10:= 2 + 3 + 5 + 7= 17
2, 3, and 13 are all prime numbers and their sum is equal to 18.
2 and 3.
2, 3 and 13 are the only prime numbers that combine to make 78.
The first five prime numbers are 2,3,5,7,11. The sum of the first five prime numbers is 28.The sum is: 2+3+5+7+11 = 28
Becouse every prime number (except 2) is odd, the sum of 2 prime numbers will always be even (and 2 is the only even prime). The exceptions are 11 and 2 for example; 11 = prime, 2 = prime and 13=prime.
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.
The sum of the prime numbers 2, 5, and 11 is 18.
There is only one even prime number: 2. So, representing 20 as a sum of even prime numbers would be 2 + 2 + 2 + 2 + 2 + 2 + 2 + 2 + 2 + 2.
It can be. 2 + 3 = 5
