A prime number times another prime number is?
If you multiply two prime numbers, the product (result) will be a composite number, not a prime number. A prime number has exactly two factors, 1 and itself. The product of two prime numbers will have those two numbers as factors, as well. The sum of two prime numbers might be prime if one of those two numbers is 2, the only even prime number, but otherwise it will not be a prime because two odd numbers will have an even sum, which means it is divisible by 2. Examples: 2 + 3 = 5 (prime) 3 + 7 = 10 (not prime) 13 + 17 = 30 (not prime) If you multiply two prime numbers, the sum of the digits of the product might or might not be prime. Examples: 2 x 7 = 14, sum of digits is 5 (prime) 2 x 11 = 22, sum of digits is 4 (not prime) 3 x 5 = 15, sum of digits is 6 (not prime) 3 x 7 = 21, sum of digits is 3 (prime) 5 x 7 = 35, sum of digits is 8 (prime)
What prime number evenly divides the sum of any other two prime numbers?
Except for 2, all other prime numbers are odd. The sum of any two odd numbers is even. Therefore, the prime number 2 will evenly divide the sum of any other two prime numbers. Here are some examples to illustrate this: 3 + 5 = 8 which is evenly divisible by 2 13 + 19 = 32 which is evenly divisible by 2 43 + 47 = 90 which is evenly divisible by 2
Are prime numbers closed under addition?
no, not all prime numbers are closed under addition. why? because, when you add 2 prime numbers you will not always get a prime number. example: 5+3= 8 5 and 3 are prime numbers but their sum is 8 which is a composite number..
Why is 87 not a prime number?
Sum of the digits of 87 = 8+7 =15(a multiple of 3) which means that 87 is divisible by 3. Therefore, 87 is not a prime number as it has more than two factors which are 1, 87, 3 etc. In order to prove that a given number is prime we shall show that the given number has more than two factors. There is no need to find all the factors.
Are all even numbers the sum of two prime numbers?
No. Not even close. Examples: 4+4=8 8+8=16 16+16=32 . . .4, 8, and 16 are not prime numbers.
You are a prime number you have two digits The sum of your digits are 8 what number are you?
There are actually three valid answers: 17, 53, and 71 All are prime and all have digits adding to 8.

What is the sum of a prime and compiste number that equal 13 what are two numbers?
10 and 3 8 and 5 7 and 6
Which prime number between 40 and 60 has digits whose sum is 8?
53 is prime, and 5+3 = 8.
What number is prime is less than 19 and the sum of digits is greater than 7?
'17' is a prime number. The sum of the digits is 1 + 7 = 8 > 7.

What is the sum ofthe first 8 prime numbers?
The sum of the first 8 prime numbers is 77.
What is the smallest prime number whose sum of its digits forms a number that is a perfect cube?
I think it will be 17. The sum of digits is 8, which is the cube of 2.
What prime number evenly divides the sum of any other two prime numbers?
Except for 2, all other prime numbers are odd. The sum of any two odd numbers is even. Therefore, the prime number 2 will evenly divide the sum of any other two prime numbers. Here are some examples to illustrate this: 3 + 5 = 8 which is evenly divisible by 2 13 + 19 = 32 which is evenly divisible by 2 43 + 47 = 90 which is evenly divisible by 2
If the sum of two prime numbers x and y is odd Then the product of x and y must be divisible by which number?
Prime numbers are usually odd.The only even prime number is 2.When two prime numbers are added say 3 and 5 the result wil be 8(even).So the question of ur answer is only applicable to the following set:2,3.The sum of an even prime and an odd prime will exhibit an odd number.2+3=5.When this two prime nos. are multiplied 2*3=6,it will be divisible by both 2 an 3.
