What 3 prime numbers add up to 30?

Answer 1

33

Answer 2

2 is the only even Prime number, all other prime numbers are odd

Adding 3 odd number gives an odd number

So 2 is one of the 3 prime number, then the problem is equal to:

what 2 odd prime numbers add up to 28?

Odd Prime numbers less than 28 are: 3, 5, 7, 11, 13, 17, 19, 23

The only solutions (for 28)are: 5+23, 11+17

So the solutions (for 30) are: 2+5+23, 2+11+17

Answer 3

Well, honey, the only way you're getting three prime numbers to add up to 30 is if you have a time machine and can go back to before the Big Bang. Prime numbers are only divisible by 1 and themselves, so the closest you can get to 30 is 11 + 13 + 2, but that only adds up to 26. So, unless you've got some magical math powers up your sleeve, you're out of luck on this one.

Answer 4

The prime numbers that add up to 30 are 7, 11, and 13. These numbers are prime because they are only divisible by 1 and themselves. When you add 7, 11, and 13 together, you get 30.
