You can put this solution on YOUR website! looks like the prime numbers are 2,7,17,19
if you add 2 + 17, you'll get 19.
the other two numbers are 7 and 19.
2 * 7 * 17 * 19 = 4522

You can put this solution on YOUR website! The given product is a multiple of 2 because the ONES digit is even and is itself 2.
The only way to have sum of two prime numbers to be 19 is they are 2 and 17.
The other composite part will be  .
Factorize 133. This will(or CAN) include prime numbers LESS than  . This allows narrowing the choices to look for. No longer being even, therefore no longer divisible by 2, the choices are 3, 5, 7, 11.

You can omit 3 and 5 from this listing. No ending in 5 and adding value of digits does not give multiple of 3.
133-11=122 No good.
133/7=19------------two prime numbers, 7 and 19.
RESULT: 2, 7, 17, 19.
