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)

The prime factors of 14 are 2 and 7. 2 + 7 = 9.

2 x 7 = 14

Prime number between 196 and 289 whose digits add to 14? Possibles 239, 248, 257, 266, 275, 284. 248, 266 and 284 are multiples of 2, 275 is a multiple of 5. This leaves 239 and 257. Only 239 has one digit which is the square of another. So there you have it.

No 14 is a composite number (1,2,7,and 14 :) )

the answer is 95

If sum of digits of a number is divisible by 3 then the number is divisible by 3. Sum of digits = 5+1+8 = 14 and 14 is not divisible by 3. So 518 is not divisible by 3.

14 x (1 + 4) = 14 x 5 = 70

Simple.2 digits numbers that are divisible by 19 are: 19, 38, 57, 76, 95The only one whose digits add to 14 is 95, 9+5 = 14

This sum can be any of 14 (from the number 95 or 59), 12 (from the number 84 or 48), 10 (from the number 73 or 37), 8 (from the number 62 or 26), 6 (from the number 51 or 15), or 4 (from the number 40).

The sum of the digits is 6.
