7, 11 and 13
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.
Any prime number has only 2 factors which are itself and one
I would have to say 3
76 is an even number so it is divisible by 2, so 2 is the first prime factor.76/2 = 38, and 38 is an even number divisible by 2, so 2is the next prime factor.38/2 = 19, and 19 is a prime number, so 19 is the next prime factor.The prime factorization of 76 is 2 x 2 x 19.
The primes are all positive number and 1 is not a prime. We look that the next number, 2 and not that the only divisors of 2 are 1 and 2 itself. That makes it prime and since 1 was not prime, by convention, 2 is the smallest prime.
The only numbers which have exactly three factors are perfect squares of prime numbers. That only gives us two results: 5^2 = 25 7^2 = 49 The squares of any other prime numbers are either too small or too large to have two digits. (The next smaller prime number is 3, and the next larger prime number is 11.)

How about: 1024
Kind of. The only prime number that is even is 2.
No 5291 is not a prime using 2 numbers. It is a prime using three numbers.
The smallest number with three different prime factors is 30.
2 is the only even prime any number ending in 2 is divisible by 2 and not prime any even number greater than 2 is divisible by 2 and not prime unless i misunderstood there can be no answer
